For the three people in the Chicagoland area who did not buy 300 packs of this gum a couple of weeks ago, Walgreens is giving you a chance to play catch up.  No in-ad coupon this time, just a higher value mfr coupon in the 10/9 S ($1).  Up2U is priced $1.49 per pack (!!), so buy two for $2.98, use two of the $1 mfr coupons stacked with the $1/2 coupon in the October IVC and you’re back at free gum (with .02 overage for each pair).  I’ve read that the scanning issue has been fixed, but even if it doesn’t scan at your Walgreens, you are only using two coupons, not the in-ad one (the more coupons, the more flustered some cashiers get), so I can’t really see any issues – well, except for them being out of stock, of course.  But then you get a rain check!
