I joined the pssst program through General Mills. You cannot get a week's worth of grocieries but they do send items and coupons when they have a new item. Join at: www.pssst.generalmills.com
They don't spam and once in a while you get a coupon for a free item. I also buy coupons on ebay. Yes I actually buy them. For less than two dollars you can get 15-20 coupons. I do think it is worth it. When I can get the Melitta coffee that goes for $4 a can for $1.78 I will pay $1.50 for 20 coupons! Melitta retails at Walmart for $2.78 and with the dollar off coupon it is $1.78. In the traditional supermarkets Melitta is $4 a can. I will only buy coupons that are in lots of 15 or 20 and with an expiration date of more than 2 months out.
