This thread inspired me stop lurking and register with mobileread-
A couple days ago I was checking out the FAQ on the Reader page at Sony Style, and they mentioned "HOLIDAYGIFT" specifically, and said that like many viral marketing codes, it had a time/number limit. The promotion would have ended on 15 Jan, but the number of codes they were willing to honor expired quickly.
Today I checked the same FAQ, and I can't find specific reference to HOLIDAY GIFT but I did see this:
How to replace an E-Coupon promotion code that either been lost or you receive a message that the code has expired or has already been used.
If a SonyŽ product has a promotion requiring an E-Coupon promotion code, and the code has been lost, has expired, or you receive a message that the code has already been used, contact the Sony StyleŽ store customer support department via phone at 888-900-9872 or e-mail at sonystyle@custhelp.com.
Makes me think they've had enough calls about this
