I ordered a set of hearing aids about 4 weeks ago via text from my cell phone. I discovered that I do not like them - too noticedable. Since I cannot drive and cannot get anyone to bring them back, can I return them by mail? And if so how?

If you bought it online then you can start the return process online and they automatically ask you if you want it to be picked up or if you can return it to a store. They will provide instructions accordingly

Call Walmart customer service number that's provided online and they will tell you step by step process on returning online bought items

I would sell them online.

That's a bit tricky. I think it's best to call the store but I doubt they will let you ship it to them without first obtaining a RMA #. It's just a prearranged label with your info on it to help them with your return. I'll be happy to return them for you but unfortunately we don't know each other. Shop here all the time. Good luck.
