I used goodrx and get it for @$63 a month. you can look at their website to find out who had the lowest price in your area. surprising the difference from one pharmacy to another.
I paid a lot for my part d (over $100 mo.) and found it no better than the $5 insurance. changing now.
still have over $600 deductible. goodrx goes up so watch if you use the gold membership ($10 a month)
you can download a copy for the pharmacy for free. you don't have to join to get a discount.
there are a couple of other discount sites like goodrx. singlecare is one. you cannot use your
own insurance if you use one of these sites. it is one or the other. if your drugs add up quickly perhaps paying with insurance would be best to get your deductible down....or not. you would need to check your policy.
