I just returned home Sunday from my third trip to AC in two months. While there this last time I had to go to Billys Store on 3/13 to buy a brush and some baby oil as I left mine at home. They charged my card for $14.80 and then turned aound and charged my card an extra $140.40. I didn't realize it until did my online banking yesterday and of course I disputed it but it's going to be quite a while until I get my money back. Does something like this happen often? It hasn't been my experience and I haven't seen any other posts about it.
