Momyknows Discount Code SAVE30 is a discount code for the maternity fashion brand Momyknows, and it is advertised as giving up to 30% off. It works the way most store discount codes do: you type the string SAVE30 into the promo or discount field during checkout at momyknows.com, and the basket total drops by whatever proportion the code applies to the items you have chosen. The wording matters. "Up to 30%" is a ceiling, not a promise, so the sensible way to approach SAVE30 is to add what you want to your bag, enter the code, and read the revised total before you commit to anything.
Discount code, coupon, voucher, referral — what SAVE30 actually is
These words get used interchangeably online, but they behave differently, and the difference is worth knowing before you go looking for savings.
A discount code — which is what SAVE30 is — is a short alphanumeric string shared publicly. Anyone who knows it can type it in. It is not tied to your identity, your email address or anyone who introduced you to the shop.
A referral code is personal to an existing customer. It usually rewards two people: the person who shared it and the person who used it. SAVE30 is not that kind of code — there is no friend to credit and no reciprocal reward.
A voucher normally carries a fixed cash value, such as a gift certificate you spend down. SAVE30 works as a percentage reduction instead, so its value scales with your basket rather than being a fixed amount.
A coupon, in the modern online sense, is the same thing as a discount code. If you see SAVE30 described as a coupon somewhere, that is a naming convention, not a different offer.
The practical consequence of SAVE30 being a public discount code is that you do not need an account relationship, an invitation or a prior order to try it. You just need the string spelled correctly at checkout.
Who Momyknows is
Momyknows is a maternity fashion brand selling clothing for expectant mothers — through pregnancy and beyond. Note the spelling carefully: one "m" in the middle, Momyknows, at momyknows.com. There is a separate company with a similar-sounding name that sells maternity health supplements, and it is not the same business. If you land on a site selling supplements, you are in the wrong place and SAVE30 will not apply there.
The brand was founded by a young mother-to-be who found the maternity options available during her own pregnancy neither stylish nor comfortable enough. Momyknows describes its approach as combining fashion designers with parenting experts, and it emphasises high-quality fabrics, attention to detail and precise tailoring. The positioning is fashion-and-function rather than purely practical basics: garments intended for a photoshoot, a baby shower, a holiday, work, the daily commute or a celebration.
What you can spend the code on
The range is broader than a single occasion, which matters when you are working out whether a percentage discount is worth using now or saving for a bigger order.
Baby shower outfits — dresses, gowns and jumpsuits, including plus sizes.
Photoshoot dresses in lace, boho, beach, mesh and sequin styles.
Gender reveal outfits in pink, blue, white and mixed colourways.
General maternity clothing — tops, bottoms, dresses and jumpsuits.
Nursing apparel — tops, bras, dresses and pyjamas.
Maternity swimwear and cover-ups.
Recurring silhouettes across the range include maxi, bodycon, lace, floral and off-shoulder. In other words, this is an event-and-everyday mix: you could use one order to cover a gender reveal outfit and a set of nursing pyjamas, or focus everything on a single photoshoot look.
How to apply Momyknows Discount Code SAVE30
Go to momyknows.com and check the spelling in the address bar before you shop.
Browse by occasion or category and add the items you want to your bag. Consult the brand's size guide at /pages/size-guide while you do — maternity sizing changes as a pregnancy progresses, and guessing is the most common cause of a return.
Open your cart or move to the checkout page and look for the field labelled discount code, promo code or coupon. On many stores this sits on the payment step or in a collapsible panel beside the order summary, so expand anything that looks closed.
Enter SAVE30 exactly as written, with no spaces before or after. Codes are usually case-insensitive, but pasting from a page can drag along an invisible trailing space that causes a rejection.
Apply the code and then read the order summary line by line. You are looking for a discount line and a new subtotal, not just a confirmation message.
Compare that new subtotal against what you expected. If the reduction is smaller than you assumed, that is the "up to" wording in action rather than a fault.
Complete payment only once the total on screen is a number you are happy with.
Understanding "up to 30%"
A 30% reduction means you pay 70% of the pre-discount figure, so on a basket where the code applies fully, roughly three tenths of the total comes off. That is the best case. "Up to" exists precisely because that best case does not always land: percentage codes are commonly written so they cover some categories and not others, or so they scale with basket value, and the realised saving on any given order can therefore be lower than the headline.
Several conditions that would normally shape a code like this are not published anywhere reliable for SAVE30. It is not known whether the code excludes sale items, nursing bras, swimwear or plus sizes. It is not known whether there is a minimum spend, an expiry date, or a first-order-only restriction. Nor is it clear whether SAVE30 interacts in any way with the shipping threshold described below. None of that makes the code less usable — the checkout will tell you the answer in seconds — but it does mean you should treat the figure on screen as the real offer and the 30% as the upper bound.
Shipping, returns and sizing
Momyknows states free shipping on orders of $79 or more, which also tells you prices are in US dollars. That threshold is worth holding in mind alongside the discount, because a percentage code reduces your subtotal and a lower subtotal can drop you back under a free-shipping line. If your pre-discount basket sits a little above $79, check whether the post-discount figure still clears it, and whether any shipping charge that reappears eats into what you just saved.
There is a returns and refund policy at /pages/return-and-refund and a size guide at /pages/size-guide. Read both before ordering rather than after. The specific return window, whether sale items can be sent back, and any measurement details are things to confirm on those pages directly — they are not stated here because guessing at them would be worse than useless for maternity sizing, where a garment that fits at one stage of pregnancy may not fit weeks later.
Who this code suits
SAVE30 makes most sense for a few specific shoppers:
Someone with a dated event ahead — a baby shower, gender reveal or maternity photoshoot — who wants one considered outfit rather than a wardrobe of basics.
Anyone consolidating several needs into a single order, since a percentage discount returns more on a larger basket and a larger basket is also more likely to clear the $79 shipping threshold.
Shoppers who want maternity clothing that reads as fashion rather than as a compromise, which is the brand's stated reason for existing.
Plus-size shoppers looking at the baby shower category, where plus sizes are explicitly part of the range.
It suits you less well if you only need one small item, where 30% of a modest total is a modest sum and shipping may apply, or if you are uncertain about sizing and have not yet checked the returns terms. In that second case, the discount is not the variable that decides whether the purchase works out.
Honest verdict
Momyknows Discount Code SAVE30 is a straightforward public discount code with a headline of up to 30% off, applied at checkout on momyknows.com. Its strength is breadth: the brand's catalogue spans event dressing, everyday maternity wear, nursing apparel and swimwear, so there is scope to build a basket that justifies the code rather than hunting for something to spend it on. Its weakness is transparency — the exclusions, minimum spend and expiry are not published, so you cannot calculate your saving in advance.
The right approach is unglamorous but effective. Read the size guide, read the returns policy, build the basket you actually want, enter SAVE30, and judge the offer by the total the checkout shows you. If the reduction is real and the shipping position still works after the discount, the code has done its job. If the number barely moves, you have lost nothing but the few seconds it took to type eight characters.
