To be clear, the website is also known as everymemorabilia.com, it redirects... I purchased what was supposed to be to original Star Wars posters signed by the cast. I received them, the COA was something I could make with Libre Office printed on thick paper, no PSA, no tamper proof stickers... 100% fake. Proven even further by a fellow collector when we compared signatures.
The only reason they are getting more than one star is because I contacted their CS and they refunded my money, no questions asked. It took a couple weeks, but the refund is there.
I would stay away from them if you want authentic memorabilia. Some seem to say they get stuff with PSA and COA, verified real, so they supposedly do sell legit stuff from time to time, but just follow the rule if it seems too good to be true, it probably is. There are well reviewed sites all over the net that will send you real stuff without the guessing game. I suggest you do your research on a site and its products before buying, especially when your dealing in collectables.
