First, you will need to collect as many coupons as you can. I'm not just talking about one of everything you can find but multiples of each. For example in the condo complex i live in there is a container for junk mail next to the mail boxes. Places like that are easy to grab tons of coupons in one shot.

Now take all the coupons home and anything that saves you a dollar or more you will want to cut out. This includes rebate coupons.

Now that you have all the coupons cut out you will want to get online and see what stores have the best sales on the items you think you could sell online. Many times you will find several coupons that can be used with the same item and if you can find that item on sale you will normally get the item for free. Thats right, i said free.

So if you can find items like this you can take them home from the store without spending a dime and then sell them on ebay for pure profit. If you have coupons for items that are not needed to sell on ebay and you don't need thoes items at home you can group the coupons into groups of 10-20 and sell the coupons online and even though they don't go for a bunch they will sell. They always do because ther are people in other areas that don't get thoes exact coupons and they could greatly need them.

Also, a really good place to look is on coupon websites because you can print coupons online to use in the store as well and most of the time they will tell you what items you can get for free and how in their forums.
