I was in the same boat as you recently, I wanted to do a quick ME1 playthrough to import into ME2. I tried every place near me that sells games (Target, Best Buy, Microcenter) and no one had it. It was also out of stock on Amazon at the time (though I think they have it back in stock now). I was starting to think, wow, maybe this game is getting rare and hard to find. I ended up getting a copy from GameQuestDirect.com, $19.99.
