Ive been buying my presciptions with GCs for months now. The points rack up fast. I buy about 400$ worth of non prescprition pills a month and 100 - 150$ of non presciption. My pharmacist mentioned this a few months but didnt start doing it till a few months after that. If you buy over the counter stuff like metamucil purchase a GC and then pay with that you can reuse your optimum card while purchasing.
