I would never buy hearing aids online because I feel so much more comfortable having the advantage of having my Costco hearing specialist literally a mile from my home, but when it comes to progressive eyeglasses I have had excellent experience twice buying progressive rimless eyeglasses online from GlassesUSA and I have no connection with them except as a satisfied customer.
(OTOH, when it comes to eyeglasses, my signif/other bought progressive eyeglasses from Costco’s eyeglass department and was very unhappy with the glasses and with the service of their eyeglass department and returned them.)
