CowBoom cuts 20% off sitewide via coupon code "SAVE20" as part of its 2-Day Sale. Plus, most orders qualify for free shipping. That's tied with last month's mention as the second-best sitewide coupon we've seen from CowBoom in over a year. Some exclusions apply, such as Deal of the Day items, auctions, and items sold by Best Buy. Deal ends January 19.

Note that the coupon can only be used once per account.
