Hopefully your able to restock by tomorrow, was quite disappointing having to wait all night when I was told it would take half an hour to an hour max.
I usually don't watch horror movies as I'm more of a comedy type, but I enjoyed Saw a lot. (Saw 2-3 the most, don't remember which one it was where 10~ people were stuck in that horror house and needed to grab all the keys to get out.)
I believe a lot of players will end up selling their potions after Double XP weekend, so thats the best time to buy it because it will go back up shortly.
In all honesty, no. Peoples interest for the game is slowely dieing, and theres no influx of new players when you have games like MW3/Skyrim as competition.
