I've noticed a curve model happening on Amazon. First it was basic medical masks that went out of stock. Then people realised DIY/Building masks are the same if not better, they went out of stock. So the next step was half face respirators for spray painting. They are now either out of stock or overpriced. Same thing with hand sanitizer. Wipes and small bottles. Then larger family sized ones, then industrial acohol cleaner and aloe vera. Its very fascinating, its almost like early adopters vs. mass consumers.
