I've had a look at their site and all of their products are replicas. If you were planning on selling these items on eBay you better think again as your membership will be disabled if you are breaching any kind of copyright laws. Quite a lot of the grammar on their site is poor english which would make me suspicious as a reputable company would hire a writer for their website.
I would proceed with caution and try to find out some more info before purchasing from them.
Has anyone else had any experience with a4buyer.com?
