I wouldn't mind couponing for and stocking up on toiletries, cleaning, and baby supplies. Especially diapers. Those things are expensive, and I try to mostly buy those on sale and with coupons. As far as food though, I would rather spend more time growing more healthy stuff in my garden than spend it clipping and shopping for junk food. None of the stores around here double coupons, although some stores like target let you use one of their coupons and a manufacturer's coupon at the same time.
