I purchased the three Dr. Scholl's gel inserts yesterday. I read about combining manufacturer coupons, Walgreens in ad store coupons and the register reward here. When I made the purchase, the cashier did not accept the Walgreen's in ad coupon. I went back today when I had a little more time to see if I would be able to use the in ad coupon, but the clerk told me the in ad coupon was for inserts and I had purchased heel inserts. So, I returned the heel inserts.
