Entetainment book checkout (or other sites to purchase it?)

[MommyBryn]

I am trying to buy a couple of the books (we only buy them when we know we are going to be using certain coupons, otherwise I don't bother), but each time I try to check out, it tells me that my credit card won't work and to contact my financial institution. I have tried 2 different cards, both are current and used regularly and the accounts are still active and in good standing, so I know for a fact it's not my cards. So since I obviously can't checkout through their website, is there anywhere else online that I can buy the entertainment book from?
