Just got a call from my drug insurance provider for medicare part D. (Aetna)

[Ms. Toad]

37. Shop around.

My premium (assuming I don't change plans) will be $7.60. ($8 the first year, then $0, then $0, then up to $7.60 - so mine, at least, isn't related to the Republican rulership.)

I'm relatively inexpensive - but my spouse (whose drugs are quite expensive) paid around $10 last year. It looks like she'll come back to mine at $7.60, although I haven't run the numbers completely yet.

If you're buying just because that was the plan you had last year, do a price check.
If you're buying based on the general rules of the plan ($X for some drug, % of price on others, etc.), run a price check using your actual drugs.

Even with my spouse's expensive drugs, except for last year, the cheapest plan has still given her the best overall price (premiums plus anticipated drug costs)
