Been getting food stamps for almost 20 years, and my experience with them, since they went to EBT, and not the paper version, is that after they roll over the first month it's all good, but if they are not touched after the second month (January stamps are still there by March 1st) they system tend to wipe them off....See the system (the tech side of it) assumes that you are no longer in posesion of the card or no longer need the stamps, so they automatically, in some cases, shut off the card....Just fuckin use them, that's what they are for... If oyu wanna keep getting them, just re-cert asap....Or learn to live dumpstered din din, LOL
