We have a high deductible plan, and a generic drug that I take just kept going up. I did a search online for a lower price and GoodRx came up. Since the price they claimed I'd be charged at a local CVS was close to half the mail order price through our plan, I really thought it would be a waste of my time, my doctor's time (new script), and the pharmacy's time. But nope - the price was slightly LESS than half what my insurance company would have charged for mail order. I was charged $134.42 for a three month supply instead of $295.65.
That's over a $50/month savings! I don't think it will apply to our deductible, but eh, we probably wouldn't reach it anyway, so why pay more.
The other odd thing was that with my insurance card, I would have been charged $75/month, which is less than the mail order price. Very strange since they push mail order to save money.
