I have been getting drugs under my insurance, and the Cobra continuation. They cost $12 per month for name brands and $6 per month for generic. I will no longer be covered after June 30. The cost will be $64.30 for a generic Sinemet for 90 25-100 mg tablets instead of $6. Other drugs will go up similarly. Planet Rx has generic for 100 tablets 25-100 for $22.11 or Sinemet for 100 tablets same size for $74.96. Drugstore.com has 90 generic for $32.22 or 270 for $91.82. Their Sinemet is 90 for $71.60 or 270 for $204.05. Does anyone have experience with either of these online drugstores, or any other online drugstores? I can cut most of my meds cost in half or better. But I want to go with someone I can trust. Are there any problems with large quantities - like shelf life? Large quantities would cut the shipping also. Any help would be appreciated, Terry .
