"After a good shopping experience the first time, I tried to shop again yesterday (order number #500502664, 25 $), and received the following message:
"There has been a hold placed on your account due to the volume of orders you have placed. We will be unable to process orders from your account at this time. The hold on your account should be released within 7 days."
Well, if a volume of orders of 50$ (first purchase) + 25$ (second attempted purchase) is too much then I'd better look for another reseller."
