That's what ebay told me. Also another user items got removed for the same reason. Thanks.
On the Ebay side, yes banisher.

It was the same thing that happened to me when I was selling a few cases on Amazon. One guy complains, he gets the product for free, then Amazon (or Ebay in this matter) reviews your account and then wham!!! shuts the whole thing down without allowing you to defend yourself. ....and steals your money to boot. (Amazon still owes me around $1000 that was in my selling account, which they said would be released within 90 day.... 120 days ago...... and Amazon will not speak with me on the phone or e-mail with my account.

) So yeeeeah..... crazy.
And yes again, Ebay seems to be cracking down on Ebay sellers who sell cases that include artwork. (I know of 3 sellers that have gotten burned)
As for the actual Retrogamecases.com site, I really, REALLY believe he is updating. When all that ebay stuff went down Retro notified me along with a few other re-sellers giving me a heads up. Retro's payment method on his site is via PayPal (as is mine) and it appeared that his PayPal account got caught in the crossfire with eBay. No biggie, just change out PayPal account on your personal site and your back up and running. And that is exactly what he did. Retro and I have been pretty close with communicating with each other and I know he has been planning on updating the site, he would have called me if something negative when down.
