There was a useful tip I was able to get from the program, and it was where they are locating this massive number of coupons. There was the dumpster diver who would check out the local paper recycling bin for the Sunday paper coupon insert.
Then there are sites that classify themselves as a "Coupon Database." If you Google "coupon database," it will bring up several sites who have direct links to coupon sites, such as Krazycouponlady. Follow their link and you should be able to find some useful saving sites. I'm willing to give it a try.
