Isn't Costco awesome for HA's?
I highly recommend Costco for anything hearing aid related. From batteries to accessories. Very inexpensive, and good quality. My daughter also had her mold made there, and it works perfectly. It's because the Audi there (real nice lady) told me she gets paid a good steady salary, and not on commission. So, they don't mark everything up so high to cover her pay. And, because they have an extra guy and gal there to help out, half the time we can just walk up and ask for help if we have an issue, without having to wait a week or two for an appointment. Especially if it is something fairly simply, yet I can't fix the issue myself.
Also another little note about Costco. If you have insurance that gives you say $1,000/yr on a debit card for prescriptions, then Costco bills all their HA's through the pharmacy, and you can use the Rx debit card to pay for it, if your insurance doesn't cover HA's. I used mine to get my daughter her Kirkland 5.0 (Resound Verso). She only needed one, since her other ear is 100% deaf with CI now, so they charged me $40 for a custom mold, and $950 for the HA. Basically, because we don't use any prescriptions, we used the annual amount on the card, and the HA was basically free.
