if you buy the kit (the dining out companion and food guide, coupons etc) there is a coupon in there for a free calculator so that might help some too, even though I'll be buying a couple calculators, I want one for home and my purse. I heard the kit is 35 bucks or something like that, I'm not even sure my meeting will have them tomorrow, last week my leader said they hadn't come in and she wasn't sure they'd be in for this week, but I'm keeping my fingers crossed!
