Sign up for Victoria's Secret catalogs, sign up for the Pink program, etc. I am CONSTANTLY getting coupons for free panties and such. The front says "with purchase" but the back, in fine print, always says "no purchase necessary in store". I must get at least a catalog or two a week, and I'd say half of them have coupons in the center. They also send out booklets with coupons as well. Just a few days ago I went to the store and was able to get 5 panties for free. If I do this a few times a year, I'm pretty much set!
