Costco has a recently-broadened selection of Goodyear-branded frameless wiper blades, made in USA, at about $8 each. Similar to the Rain-X wipers in design, but US-made and cheaper.
My experience so far with them (after about 3 months on one vehicle) is that they're perfectly good wipers for the money. Good pressure and aerodynamics from the frameless design. Too soon to tell how they'll last. You might want to give them a look.
I've found that price and quality are two **very** different characteristics where wipers are concerned. My favorite for many years ago was the absolutely cheapest wiper I could buy at a Canadian Tire store, at about $2 each. I've thrown away $20+ wipers after a few weeks. There seem to be no rules here. Ya gotta try stuff.
