FYI - Abstract Ocean still has a Black Friday 40% off sale on (see below) for blind spot mirrors. I couldn't make up my mind if it was worth it, so I put it in my basket and left. I later got an email from them with a 15% discount coupon (sorry, one time use). I went back to my basket and even added the light bulb upgrades that I was thinking about (yeah, the 15% coupon worked). No tax and free choice upgrade to USPS Priority Mail to HI.
