Wow that’s crazy. I would’ve thought it didn’t matter considering it was not on the bag itself.
Yeah... not applicable to OP, but I think it's crappy to try and return a bag you had hot stamped considering they warn you it's non-returnable about a million times before they do it. For the few items I've hot stamped, I never do it the day I buy the bag, just in case. In OPs case where you bought it online, that's tough.
