As one of its daily deals, Best Buy Computing Clearance cuts 21% off sitewide via coupon code "OCEANS21". Plus, most Computing Clearance items are eligible for free shipping. (Free in-store pickup at Best Buy is also available.) That beats yesterday's mention of 20% off and is the best sitewide percent-off discount we've seen from this merchant since February (when we saw 25% off). However, this is part of a series of daily deals that will increase the sitewide discount by 1% over the next several days, until it hits 25% off. Deal ends today.
