First, studies have shown that coupons use is highest in the upper middle class income bracket. The people who need to save money the most (those on government assistance, those in the lowest income bracket) do not use coupons at all due to not knowing how to use them or the stigma attached to them. When I volunteered at the food bank down in Shirlington, I really wanted to get my act together and teach a coupon class to the food bank patrons so that they could stretch their food stamps to the maximum but I never ended up doing that. I'll write another email on how you can donate extra items you get for free through couponing to the food bank or church groups to help support the poor right in our own community.
