Update--Our Pepsi-iTunes Promo Success Rate

After purchasing an initial half dozen of the 20 oz promotional bottles of Pepsi, i.e. with the yellow cap with a 1:3 chance at a free iTunes song, we have continued to buy an occasional bottle. Our score stands at 10 free songs out of 14 bottles.

BTW, we haven't used the cheat posted on MacMerc.com but we admit to looking to see if it works. It doesn't with our eyes, even with reading glasses, unless the bottle is empty and at room temperature and the translucent blue-green gasket is removed from the cap. YMMV
