Well, if the coupon states $5 off then that it is what they have to honour. A PLU means nothing to anyone looking at it.
I see some idiots have reported the $5 off $5 on FB so it looks like they changed it. Unfortunately, they still screwed up which is why people like me are getting $3 off $10. Arrgh. Can someone please post the $5 off $5 with the code? With these screw ups, they deserve to be taken advantage of. I guess it is probably some poor sap who got stuck working Christmas Eve and wants to go home or join the office party and isn't focused on what he is doing.
