Lol. Yesterday, they ran a 10 for $1 bundle. The discount didn't appear initially, and my cart was $130 worth of bundle fodder. I checked again about 30 minutes later to find the discount had applied, but they had already run out of The Anthem keys in just under 2 hours. I checked my cart today, and 3 more of the desired games were out of stock. Also checked Twitter, they never responded to my tweets asking if they would restock.
The moral is that you need a healthy stock of game and bundle keys to actually fulfill orders if you want to advertise "never miss a deal again."
