The Squaretrade promo doesn't work on eBay items. From their facebook page:
"Q) What can I use this coupon for?
A) Coupons can only be used on protection plans purchased at SquareTrade.com. Unfortunately, coupon codes cannot be used on eBay or Kindle Products. We also cannot combine this with any other offer, and only one coupon per purchase."
Also, I'm interested to see if anyone has tried to claim their SquareTrade warranty on these monitors. I couldnt find any accounts of such by searching. I wonder if they attempt to repair these monitors or if they will replace them (perhaps with US equivalents?)
