    Here's a secret that computer hardware retailers don't want you to know: the price a retailer sells a piece of computer hardware for is often up to 10 times (!!) the cost of making the computer hardware. Great deal of them, not a great deal for you.

    At LANGTU Store, we sell directly to our customers, cutting out the unnecessary costs and crazy markups that make typical fine computer hardware extremely expensive. We pass the savings on to you, so you can get reliable products with the highest performance standards at a fraction of the normal price.
