Yes, Spriggy cards can be added to PayPal accounts as a linked payment method for online purchases.
In order to successfully link up your Spriggy card to PayPal, you'll need to have a positive balance because PayPal requires a pre-authorisation; whereby they debit $.01 up to $1.00 from your card (that gets refunded within a couple days).
If there's a $0 balance on your card at the time, it may be rejected. So we recommend keeping at least $5 on the card, so you can successfully link the card.
*NOTE* PayPal accounts cannot be used to top-up Parent Wallets.
