People have been encountering issues with Walgreens and the new registers – they don’t take the second $3 coupon on the BOGO:  Register can’t find the second product to attach to.  It’s certainly not insurmountable, because all the cashier has to do is enter the coupon manually as a mfr coupon, but I think that’s where all the confusion on accepting two coupons on a BOGO might be coming from.  People have had asst mgrs telling them that Wags changed their coupon policy a few months ago…no they did not!  If you encounter this at your local Wags either switch stores or beat that mgr to death with his or her own leg – either way works.
