Home Antenna cuts 15% off sitewide with no minimum via coupon code "OLYMPICS". It's the best percent-off coupon we've seen from Home Antenna, which sells indoor, outdoor, USB, and other TV antennas. (We saw 15% off last week; however, it required a $75 minimum order.) Shipping adds a flat $12.95, or get free shipping with after-discount orders of $100 or more. Deal ends August 12.
