Quantity 120 of levetiracetam 750mg was $170 cash. Sam's Advantage Plus membership discount was $102.
GoodRx website said I would pay $20. However, the actual price I paid at the counter was $39. (The pharmacy tech told me that GoodRx coupon doesn't always show the GoodRx quoted price.) Otherwise I would have given 5 stars.
But it did work and I saved a lot of money!
