I've mostly switched back from shopping online to shopping in local retail. If you're actually stocking shelves, instead of just running a digital flea market, you have to be choosy about what you stock. There's a ton of value in having someone filter out the trash and buy from reliable sources. I'm happy to pay more for that service, and usually I can get the item same-day since I'm already there in the store. For example you may have a local vacuum/appliance shop who has a direct relationship with Dyson and so can buy genuine parts on your behalf, or even have them in stock wholesale.
