Used to work with Walmart pickup until Walmart made their emailed receipts only include the first few items. Now fetch only recognizes those and you have to email them to get the rest added which defeats the whole point of the app. When I asked them about it they said e-receipts were a beta feature and not guaranteed to work and then gave no timeline on a fix. This also doesn't work with Walmart pay. Bottom line if you don't have a physical receipt don't bother with this app.
