Has Anyone Used www.need-shop.com ?

I'm looking to buy a Lenovo Y580 and all the retailers I look at, the cheapest model is around $900 with 1080p and the works. This website says it's all open box, which I'm fine with, but these aren't manufacturer specs, they're better! They are coming with 256gb SSD's, upgraded CPU's, and for all of it it is still cheaper than going to a name brand store. Lenovo does not do these options whatsoever. So my question is, is this to good to be true? They seem reputable. Huge store, well put together. They are headquartered in China so that is another concern. Any advice? This looks awfully tempting.

I did a little search for it and saw this.

Thanks for that. I guess it is too good to be true.
