I tried using my visa at the Sacramento Craft Expo and the charge was denied. The gal said that she has encountered a lot of declined cards lately because the charge originates in the home state of the vendor. It can appear to the CC company that the card has been corrupted.
We now call the CC company BEFORE we make any odd buys so they won't be refused.
Happy Shopping! I am a little envious. Padukah is definitely on my bucket list.
