I'm a little blurry on this still. I know that if you are selling cards and after a certain period of time they don't sell that they will start charging you a per card fee until sold or shipped back to you. My question is what about buying? Let's say I have 10-15 cards I've purchased but don't want them shipped to me as I believe I will be making future purchases... after a certain time do they charge you to hold onto these? Thanks in advance.
