yes! Smartypig gives 1% APY (and it's got that adorable pig and colors -- yes, I'm a sucker for the cartoonish thing, but as Mike says, let the tricks help you. If the cartoon pig helps me want to use the site, so be it. I'm saving!).
Instead of ImpulseSave, I have used smartypig for a couple of years and love it -- I used it to save for my honeymoon, my friend's wedding, and a new car...and "just because." It's user-friendly and has a handy option to auto-withdraw on certain days of the month (i.e. the day my paycheck comes in!) so that the money is basically out of sight, out of mind as soon as I'm flush with cash (the two days a month that happens...). I thought I heard about smartypig on this site, but I guess not if Mike didn't mention it in this post!
