Get a jar and put all your change in it for a couple months...my gf and I have been doing this for about a month and a half or so and we have like $75! It's going to be used for a trip, but I started a second jar for a mac mini! haha! Since I won't buy a mini until it gets up to 1.7ghz or so, 1.8ghz preferrably, its ok that it will take me a year or so to get the money hehe.
