I have a problem using my CC at Poser Pros.   It's the same card I use at all the other online stores but since March of this year Poser Pros stopped accepting it.   I contacted their staff, nothing.  After giving up for months I followed a friend's advice and contacted them again - guess what?  Still nothing.   So, I dont' shop there anymore.  I suppose they have more customers than they can handle so they don't mind losing one ;)
