Some of the vendors have the ability to check your card right there and make sure it's good.
Us on the other hand do not have that capability, so we won't be taking plastic there because we have no way of verifying the card. And we have had a few orders called in on bad cards. What we will do there is fill out an order form and when we get home run the card through our machine and ship out monday.
Glad to hear that many will take cards, though. This will be my first trip to Hay Days this year, hoping to go on Saturday. Looks like a huge deal, I had never known there was a show like this, and so close to home as well!
