Groupon has a solid deal for an 11.6-inch Acer C720 Chromebook right now, offering up refurbished units for just $129 (with free shipping as well). That's $70 off the MSRP of $199, and an all-around great deal if you've been looking to pick up a Chromebook as a second (or third) computer. This is the model with a 1.4GHz Intel Celeron (Haswell) processor, 2GB of RAM and 16GB of storage — more than enough to get anything done on this little machine.
Though it is refurbished, Groupon offers a 90-day warranty and free returns within some limits. Of course quantities are limited for this sale, so if you're looking for a screaming deal on a Chromebook, go pick one up from the source link below.
