MiniInTheBox is run by the same people that run LightInTheBox.com and they both specialize in selling highly discounted items direct from China. MiniInTheBox mainly focuses on accessories and gadgets while LightInTheBox focuses on selling clothing, household items, toys, sports equipment etc. So in general, they sell different types of items. One thing both of these sites do, however, have in common is that you don't have to buy in large quantities to pay the advertised price; so you're getting items at wholesale prices without actually having to buy them in bulk. With that being said, the daily deals section of MiniInTheBox offers even bigger discounts (many items priced half off or better) for a limited time only.
Deals.miniinthebox.com currently ranks #15 amongst sites offering online deals -- QVC ranks #14. In the General Merchandise category, MiniInTheBox ranks at #11 -- Qvc.com again ranks slightly higher at #10.
