Buy one get one free bottle caps

Well, i work at a grocery store, and i know when we get these caps redeemed to us, we have to keep them aside and send them to the vendor (such as pepsi, or coke or whatever) as sending the caps to them is how we as a store get re-imbursed for the product. The same thing with all the coupons that customers turn in. We have to sort them out and send them in to our corporate office, where theycombine them with all the coupons form all the other stores, then send them to the various vendors, who then reimburse us for what they are worth.
