eBay Sale & PWCC Vault

[mintacular]

Look, I don't want to start another PWCC bashing thread. However, I do have a question which is that I sold an item on eBay and the buyer was a random name (like Brian Davis) with a dash then PWCC Vault in the title. The shipping address is Oregon and I believe home to PWCC, with no sales tax as is the case of with residents in Oregon....

So my question is, let's say you are a high end buyer/collector and you spend 100K a year on sports cards. In Pennsylvania we have 6% sales tax which is about average I think, hence 6K in sales tax. If I were to open a Vault w/PWCC how much would that be per year and could you just collect cards there and have Brent ship them to you at later and avoid the 6K? Obviously PWCC would have a fee of their own/send-back or "cash-out" fee, but probably less 6% I would guess.

Thanks, just want some clarification if anyone knows how this whole VAULT situation works....-Pat
