I use free Goodrx.com coupons from the internet and get mine in Nevada for just under $20 for 30 5mg tablets (generic). But the deals seem to change month by month, so I always check before I get a prescription so I know where I want the provider to send the prescription. Once I have a prescription, so far multiple pharmacies have honored that same price for the refills until the prescription runs out as long as it's not some 1 month special rate. Also, although I have insurance, I don't use the insurance and just pay cash with the Goodrx coupon. Ditto for sildenafil, which I was using, but my doctor switched me to tadalafil after my recent NS RALP. I'm not a medical professional, but I think part of the reason for the switch is sildenafil clears out of the body in about 8 hours while tadalafil last until the next daily dose. I do think they're helping me with a generally increased blood flow to the penis. Since I can get it for less than $20 a month and I don't have any negative side effects from taking it, I'm going to continue taking it until my doctor tells me it's no longer indicated. However, since I was on sildenafil before my RALP, I suspect that may be never. Best wishes.
