You'll have another such experience when you find out that you can BUY the coupons you need. Recently
GROUPON had a tremendous deal. They sold $15 eBay gift cards for just $7 each. Of course, I (and almost a half million other people) snapped at that deal. The first thing I did the next day was use my $15 eBay gift card (which cost me $7) to buy 60 Air Wick coupons which allowed me to buy 60 Air Wick Ultra Freshmatic starter kits (retail value: $13.99 each). Plus there was a $1.01 overage on each. So basically for $7 out of pocket, I got over $800 worth of product plus 60 bucks back in the form of overage. Net cost therefore was I got PAID $53 to pick up over $800 worth of Air Wicks.
Oh, and if you sign up for GROUPON (it's FREE signup), don't procrastinate when you see a great deal like that eBay gift card deal. I waited when they offered a 4 hour sailboat excursion for just $55 and when I decided to buy it a day later, it was GONE.
