Is there an interet in a coupon/savvy shopping class

[connie254]

I've become pretty good at the whole couponing/savvy shopper, and can usually feed my family of three on $50/week, including household supplies and toiletries. I know of a fellow in Cleveland that does classes at libraries. Is there a school/library.etc that I could contact about doing the same thing? The MCCTC, public library websites aren't very helpful.
Apparently the fellow from Cleveland also sells his books about couponing at the classes. If I can keep the price of the books reasonable, would there be a market? I'm assuming no more than $5/book.
