a few years ago Consumer Report did a bit on hearing aids. At that time, they said that Costco had the best deals and aids. Of course, since then, you can buy them over the counter.

Bottom Line, they (or most folks) will test you for free & you can compare prices. I am on my 2nd set from Costco. I may try OTC next time - if there is a next time. Many project them to only last for 3 or 4 years. Hmmmm
