Excellentcom sent out an email saying they've got kits for the same price. Someone may have just found a huge container full of Flip Shots. Haha... That hasn't happened since Super Dodge Ball.
Edit: To add to that, should you buy it? Sure. It's a great price for the game if you dig Pong style games. As others have said, Bang Bead is more valuable (Flip Shot's sequel) and Windjammers is a hell of a lot more popular, but it's still a rare game and a good price if you're wanting to add it to your collection. I passed on Excellent's offer today because I already have Bang Bead and I don't really want a Flip Shot. That's kind of it... If you're buying to (really no pun intended) flip it, then it's probably going to be a questionable offer. Only reason being Excellentcom has them for the same price, your buddy has some too. There are definitely a lot of Flipshot kits about to enter the market and tanking its resale value. It'll still be worth $65 and change for a while due to shipping costs/etc, but don't expect to sell these for $200+ a pop
Maybe one or two on eBay to the suckers, but not many after that. Of course, if you want to buy a few and sit on them for a few years they could be worth some cash... but then, I can also give you way better advice on investments that will far outperform Neo Geo carts
