I use GoodRx in NYC, but they seem to have nationwide coverage. (There's a login option, but membership isn't required, and I've got no idea what, if any, additional benefits it brings.)
They track your purchases, of course, but I've read that you can opt out.
Here's a comparison of GoodRx's and Blink's prices on my eye drops:

Their price on my skin cream is similarly low!
