I've had very good experiences with Costco, they're audiologists were very good, they have decent prices and very good service.
If my union hearing aid plan re-imbursed me more than $500 a pair I would have gone back, but they switched to a national company called Hear USA. They are also very good and I just got a set of Signia top of the line for $500. They sell at $3500 so a decent price. They obviously do a heavy discount to the union. I think the aids I got recently are by far the best sounding I've ever had and I've needed and used aids for 20 years. I particularly like that they BT connect to my phone and iPad so I can do phone calls and Zoom using the aids, which is a really nice feature. I do not as BTW wear them while cycling, mostly as I can generally hear cars coming as well as I don't want them falling off the ear and I don't want to get them wet from sweat.
