I don't think you should buy that too.
You might got something like aladdin, who knows?
According to the description they send you a -new- release every month. However, I think we all know the decks that D&D enjoy, and those are sold by T11, CARC, and other big retailers which we have absolutely no problems buying from directly. I absolutely adore a lot of D&D products - this one just personally isn't for me.
However, if you only buy one of each deck and want to save a couple bucks on shipping, I say go for it.
