Microsoft on Friday announced a big sale of Surface Book and Surface Pro 4 computers in celebration of Memorial Day Weekend in the United States. The company is knocking $150 off several models of both computers.

You’ll save, for example, on the Core i5 and Core i7 models of the Surface Pro 4, though Microsoft did not discount the cheapest Core m3 model. That means you can expect to spend anywhere from $849 for the Intel Core i5 Surface Pro 4 with 4GB of RAM and 128GB of storage to $1,649 for the Intel Core i7 model with 16GB of RAM and 256GB of storage. Microsoft also knocked off $150 from the price of two Surface Book models, including the Core i5 option with 128GB of storage (now $1,349) and the Core i5 model with 256GB of storage (now $1,749).

Not a bad way to grab some pretty awesome computers, especially if you need something before the Back to School Season sales kickoff.
