If you are buying from overseas first make sure they have an international warranty. Most audiologists here will not program them if you run into problems so you might want to check with the local audiologists first. Much of the cost of HAs is the included services so check on the cost of adjustments if they are willing to do them. There are lots of places online to buy any consumables but sending aids back to the US for repairs or receiver changes may mean being without them for an extended period - think weeks. This sounds ok compared to not being able to afford them at all but it is much harder to do than it sounds - especially after you become accustomed to amplification. Taking off your HAs feels like someone has blocked your ears with something or is holding a pillow over them.
