Just be aware, these cards (not only from this seller but all sellers of Panera cards) work fine but the way they are created (hint: Google Panera+) the chances are 90% that another person or 6 other people will end up with your same number and start using your card. It might take 1 day or it might take 3 months so just use them up. They aren't carded, that's the good news but just keep checking them because the next time you walk into a Panera they might have 20cents left on them. I can "vouch" for that from personal experience. Again, that is not specific to this seller but all Panera sellers. A guy on Bitify was selling the app to generate them so by now 1/2 the world must have it. So buy lots of bagels, soup and cookies and put them in your freezer!
Vouch for this seller! Card was from October and was still valid when it was used.
I am not sure about the information from the post above me, but I feel if you ran into problems that this user would stand behind his product.
Good luck with sales!
