Sunday, March 9 - my Gold membership expired yesterday. Today, the code for three months of Gold worked! So did another code I'd bought for an additional year of Gold. However, the codes for the free games still won't work. I've replied to the email yet again, so we'll see if they make good.
If this lasts another 8 days, it'll be a full 3 months since this began.
Just Cause 2 DLC (last week) - there's a free cannon-equipped Tuk Tuk, as well as some vehicles and guns that you can pay for if you want Gold Member Deals of the Week (Monday) - Darwinia+ (800 points) - Defense Grid (400 points)
