I think I’ve encountered the limits of wiper blade bargain-hunting. I used to fill out RockAuto orders/shipments with a few of their bargain close-outs on wiper blades, mostly Trico Teflons and Neoform blades, for each of my four vehicles. After experiencing my second recent mid-rainstorm disintegration of a wiper blade that’s had less than a year in actual service, I think I’m bumping into the practical limits of buying, stashing, and using what are actually middle-aged rubber components, like wiper blades. I haven’t found any sort of manufacturing date, or date code, on the blades in my wiper stash, but some have been in the stash now for 3-4 years, and they were probably aged stock when I bought them. More than one set for each car, bought fresh at their non-close out price, is probably all that’s prudent to keep on hand, assuming wiper blade replacements every 12-15 months. No real use in piling up more “bargain buys” than that, it seems.
