Three times actually. Well, two were stupid, one was just really horrible luck.
I was buying dragon quest VIII on amazon and it was pretty pricy for a ps2 game, but I finally found one that was super cheap. Well when it comes to my house I'm quite surprised to see no intro or setup or anything, the game just throws you in. Eventually I realized that I had bought some stupid demo version square enix released for some reason.
I wanted to get Ice climbers, and I was looking online and saw one that had a picture of a gba version of it, and I had a ds so I could play it. Well when I got it in the mail I was shocked to see that the game cartridge itself was bigger then my ds! It turned out that they were selling the NES version but they put the GBA picture in the listing, but fortunately they were nice and gave me my money back.
Ok this was the worst luck ever, it cost me $250. So dragons dogma used to only be for the xbox 360. I had been dying to get it for months, and eventually I decided I couldn't wait any longer, since it seemed they werent going to release it for any other systems. So I bought an xbox 360 specifically for that one game, and it was pretty decent, but definitely not worth all that money. 5 months later, Dragon's Dogma was released on steam, for only $40. -_-
Also I was kinda stupid when buying fire emblem fates. I was trying to decide which side I wanted to play more, so instead I just bought both of them. Well whaddya know, if you buy one you can get the other one for half the price in the game. And of course you miss content if you dont have them in the same game, so buying both of them from the eshop wound up costing me an extra $40 then I needed to spend
