We are dealing with this and I have some experience due to kiddo getting aided last year. Costco is like $3000 for a set. Downside is you can’t use any insurance but you could reimburse yourself if you have an HSA/FSA. Also if you ever have an issue, you can return them. You can product shop. Hearing center of America or other audiologists carry different products. At ours, the basic set is $3, 000 and it’s Phonak brand. With our insurance the hearing aid fund is subject to the deductible. So after we spend $3, 000 on healthcare, then they reimburse at 80/20 up to a max benefit of $1, 500 for 3 years. For pediatrics there are funds available via non-profits (income based) to get aids. You can always inquire if these exist for adults. Our town also has a local Deaf/HOH FB group and through them I was able to connect to other people and parents that helped me navigate resources to help our family. Hope this is helpful!
