Many Costco locations have a hearing aid dispenser and/or an audiologist to work with you for hearing aids. I haven't used them for HA's because I was wearing cochlear implants before I knew Costco had HA's, but from what I have been told by many, many people is that Costco's HA's are about 1/2 the price of elsewhere. They have good prices on their HA and CI batteries as well.

@nancydowling My experience with Costo in San Diego was as follows: Costco has hearing aid specialists. The hearing test is free. Hearing aids are recommended based on test results. They offer a 6 month trial period-I have never gotten more than one month through any healthcare provider/audiologist. The aids come with a warranty as well. While I waited for my test, they cleaned my old hearing aids. That fixed whatever was broken so I didn't order new ones. I was allowed to try Kirkland brand aids and walk around the store. Those aids took out a lot more background noise than my soon-to-be 5 year old Oticons. A pair of Kirkland brand costs about $1600 I think. Ear molds are extra. They sell a few other brands as well-prices are higher on those.

I went back for adjustment after 10 years from purchase date with no charge. But they don't have one month trial time when you purchase it in California.

They test you there but they are not audiologists. I ended purchasing a pair there and the first three months were great. Then they miserably failed. Fortunately they come with a six month trial. My biggest complaint was that they were not highly trained, when I took them in for cleaning and had questions, I got some false info and my biggest complaint was that they failed when using my phone app. I had Phillips and they were about $2,000.
