Good for you calling to say STOP!
Buying hearing aids is - imo - very similar to buying a car. You go to an audiologist, who has contracted with (usually) 2 companies. So they offer those 2 brands. It is unlikely they offer every model offered by that manufacturer. One of those contracts is going to pay a higher commission than the other; so very often, that is the aid they push. If the person doesn’t like it, well, they have another one as backup, to offer. You go to a Toyota dealer and they talk to you about Toyota; they don’t have Chevy, Ford, Honda, etc.
Trial periods vary greatly. With some places it is as short as 2 weeks. With Costco, which seems to have the longest, it is 3 months. With some places you have to pay a small ‘restocking fee,’ so you do not get all your money back. The amount varies. With other places, you get all your money back - that is how Costco works. With a small few places, if you do not like the pair you trialed, you can switch to the other brand they carry, and get full credit; but you don’t get money back if you walk away.
Many audiologists offer REM fitting; a small few offer it for a fee. Costco offers it standard. Folks on this forum highly recommend you get REM fitting.
As I explained above, most audiologists work on commission. At Costco, they pay the fitters a salary. This is why their prices are much lower than anyplace else. I don’t know what you were quoted for those Resound pair, but at Costco you can buy a pair of good brand hearing aids for $1400 to $2500. That is for the PAIR. Costco typically carries 5 different brands, all well known. Their own label, Kirkland Signature (abbreviated KS on this forum) is currently the Phonak Marvel, with a few features turned off. (I may be out of date, especially as I have not yet read up on the new KS 10, someone on the forum can correct me).
As with buying a car, there are many features available, but not all brands all models offer all features. Investigating what features are out there and sorting out which ones you will use takes some time but helps you get the pair you will be happy with.
If it seems like I am pushing you to Costco, well. yes. The best deal, the best pricing, the better service. Costco (in USA) does not accept insurance. So if you have insurance, you need to factor that in as you decide where to go.
Ongoing, with hearing aids you will need domes, and batteries. Depending on the brand, make and model, you may have to replace wax guards every 3 to 4 weeks. Costco offers domes and wax guards free, and the pricing on their batteries can’t be beat.
So you get your hearing aids and head home. Now they are going to need adjusting. It takes some time for new users to get used to hearing again. Plus the aids need adjusting to fine tune them in to your specific hearing loss and lifestyle. Some places include a fixed number of adjustment visits. Costco has no limit. You may need programs set up - press a button and get the settings on the program for when you are (example) at the book club meeting at the local library. This can take a follow up visit or 2.
I get it, 3 hours one way is a lot and not easy to do. And most likely you are correct in saying that is not an option for you. So you make a list and start checking with the places near you. What are the terms of their trial period? How long is it? How much is your fee if you have to return the aids? How many adjustment visits are included in the purchase price? What do they charge for adjustment visits after that? How much do they charge for domes? If the brand includes wax guards, how much do they charge for those? Note you can find domes and wax guards online, and save money that way. And batteries you can pick up in many, many places.
