I've looked for new RX coupons several times and never found any. Unfortunately, it seems like all the coupons are for a transferred RX. Sometimes, one of the pharmacies will honor a transfer coupon as a "competitor's coupon," but that seems to be more rare too. For example, if you take a Walgreen's transfer coupon to CVS, they might match it. But the last couple of times I've tried, they've said no.
Good luck.
