Amazon Offers end time

Amazon sales usually start at midnight pacific time USA I think. I'm always asleep then so not sure on the exact time. So depending on when they flip to the new sales, the old sales will end around that time.

Some games seem to pop up every other day, if you miss out you might have another shot at a later date :)

This thread on CAG has been a lifesaver. It has a list of all the games going on sale + start and end. The one area that's tougher to gauge is when they price match or do price drops randomly. Best thing to do is look around forums, like that CAG thread I linked or the GameDeals on Reddit. If something pops up for a short period of time, someone usually notices it and shares info.

As for exact time, Amazon deals start at 12am PST on the day of the deal. You may have to wait 15 mins for the price to propagate to the main page, but they almost always start at that exact time unless its a special deal. IE They had BF4 for 29.99 on Black Friday for a couple of hours. I dont think they have any deals like that planned for this sale where its a very specific time frame.
