Setting up your store location

Click the pencil icon below your store location on the left sidebar.
Append -9999 to your zip code. For example, if your postal code is 11106, then it would now be 11106-9999. Once done click Update and Exit.

To set up the shipping zone and fee.
Login to your BigCommerce store, go to Store Setup >Shipping > click on Add shipping zone and then choose Add custom zone.
You may refer to Bigcommerce' guide here: Shipping Zones
Name this zone something that matches your store location, like Pick Up In Store Oak Street.
Next, under Type, choose Advanced Selection and choose Multiple postcodes.
Select your country and then add your custom postal code here you just set up in your eLocal pro store location settings, for example, 97442-9999. Click Submit.
Click Configure to the right of your new shipping zone.
Now click the toggle to on, to the right of the Pick Up In Store, and then click Submit.
Click the Done button in the lower right-hand corner.

You will need to repeat this instruction above if you add more Store Locations here in eLocal pro.

Blocking dates and adding pickup timeslots

There are 3 tabs: DAYS OF THE WEEK, HOLIDAYS, and CUSTOM
We recommend setting up the DAYS tab as your "regular" or standard schedule of your pickup hours.
HOLIDAYS is there for convenience, it has a list of common holidays that you can set specific timeslots - this overrides the DAYS OF THE WEEK tab.
The CUSTOM tab as the name suggests is a custom date - this can come in handy if you need to block off a date or adjust slots for specific dates.
For overlapping cutoff times/dates, the following hierarchy is Custom > Holidays > Days Of The Week
