Avoid them like the plague
I bought a Macbook Pro Retina from them on the 21st of october last year. What they delivered was a Mid 2012 retina, started a ebay case against them, they issued me a £100 refund and offered me a 2 year warranty as i could get an applecare warranty due to the macbook being over 12 months old.
Macbook now has gone faulty the warranty is a joke as they are not honouring it, and ebay cant do anything as you can only have one case opened against each sale, once its closed that it. No matter if the seller backs out on the deal, ebay money back guarantee is a joke.
Google the seller and you can see hundreds of entries about the seller doing just this. They are a power seller and know ebays policies, you are playing right it there hands by opening a case. I would not recommend using this seller at all, AVOID THEM LIKE THE PLAGUE😡
