Just when I had despaired of ever seeing such a thing, there it was under the cap of the Pepsi I opened today: "BUY DEW/OR PEPSI/20oz GET/1 FREE." Now the problem is that I have to have this cap lying around until the next time I buy Pepsi (so I can't let the cat get at it and play with it until it ends up behind the refrigerator), and I'm not convinced that the average checkout clerk has any idea of what they're supposed to do with these caps; they clearly won't fit in the cash drawer under the money tray, with all the rest of the coupons.

Anyway, this means I'm 7 for 16 on winning caps (6 songs, 1 free Pepsi).
