PharMacy: Giant. Printed a GoodRX coupon yesterday for a prescription I just got. Gave the pharmacist the scipt and coupon... she said OK, be about 15 minutes. Picked it up and low and behold it was a dollar less than the coupon! Here is the kicker believe it or not: price paid was $16.66. The regular retail price printed on my paperwork was $534.09. Im still stunned. Unbelievable.
