It's one of my favourite online shops. For example, it's the cheapest place for games by Czech Games Edition. Also, the more you order, the cheaper the shipping gets!
Though, one thing I find confusing is the yellow truck status of some games. The translation of the yellow symbol says "The product is currently not available. The article, however, can be pre-ordered". Last time I ordered items with yellow truck symbols, the package arrived very fast but my recent order has been on hold for two weeks :(
This is a major issue for the site as it really doesn't indicate if they will actually have it in stock or if it's never going to be available. Having said that, I have ordered a couple of times from them because euro games are pretty much half the price there compared to the UK and despite the costly postage it's still a bargain. Postage is pretty quick too. I think I ordered on a friday and the parcels arrived the following thursday. So as long as the stuff you want is in stock (the dark green truck icon i think), go for it!
