It seems the Ubisoft credit didn't work for me. I followed the link in the email and checked out. I thought that the code had been applied, but it pulled the amount from my credit balance.
I emailed support, hopefully they'll be able to straighten it out. Has anyone else had this problem?
Yup. My ubisoft credit didn't work on a $7.49 item. I actually got two Ubisoft emails, but credit wasn't being applied. I contacted support via chat, which led to them calling, which led to being told to buy it and it will show after checkout. It didn't. Support then gave me a general $5 credit to use on my next order.
So that's two phone calls with Amazon today with general credits issued pre-purchase (for a THQ credit that never showed) and post-purchase (for a Ubisoft that did show, but didn't work.)
This promotion is great, but it seems to not be working very well.
