I am a member of Barnes & Noble book stores. I pay once a year to renew and I do save quite a bit of money over the year. Two years ago, while in a store, I was told my membership was past due, and asked if I wanted to pay. I did and had the cashier add it to my total. I then saw that I was billed on my credit card two days before.
Barnes & Noble would not credit my account, and I ended up going through the credit card issuer to get a refund.
