Which store did you place your order with?
If this was Walmart Pickup & Delivery, you have to place an order with Walmart Pickup & Delivery. Be sure Ibotta is linked to Walmart Pickup & Delivery. Also, turn substitutions off for Ibotta items. Ibotta does not honor substitutions by Walmart.
@dvbuls If your card is linked you need to click on the items before you shop you can't add them after. If your uploading a receipt after you scan your receipt and are scanning barcodes it will say did you miss anything then you can use the search for the items you're missing then when done follow the prompts like normal.
