Amazon for about $70. Prices vary for the different colors on Amazon (and prices also change frequently, so pay attention to that). My number one suggestion, no matter the color, is to buy it on Amazon, just because it's so much cheaper. Also, film is a lot cheaper on Amazon and because you do have to consistently buy film for this, you're going to want a good deal. A fun part of buying film is that you can either buy the standard white border, or you can choose from one of the other various options, like comics, Alice in Wonderland, stained glass, etc. (my personal fave is the rainbow pack).
All in all, I really have no complaints about this camera (which is rare for me) and I highly recommend it to anyone interested in purchasing one. The only minor complaint I have is the pain it will be to purchase expensive film all the time, though Amazon's cheaper prices make it bearable. All my friends love this thing and we have the best times taking instant pictures together. I'll keep it simple; I love this camera!
Have any of you been lusting after this camera? Do any of you have an instant camera? Let me know!
