If my trust in long term reviews erode, I'm inclined to buy less.
Word of mount is a powerful tool that amazon has harnessed with reviews, and has seemingly replaced the need to see a product in person before a purchase.
Which's primary benefit seems to be for White goods, but how often do you buy a new fridge/oven/etc?
I find amazon reviews are still fine. Read the worst reviews read 3* reviews to find all the worst things. Use 5* reviews to get an idea.
However, for some categories, such as batteries or electronics, even after examining all the negative reviews and rates, I've found it impossible to get non-counterfeit products. I'm happy to go to a regional specialist in such items or even to a big-box store just to get greater confidence in a genuine item.
(&yes, don't even think about getting 18650s on Amazon. I saw someone selling boxes with a Tesla logo & brand - obvious BS. I reported it and at least did see them disappear in a week, but another popped up.)
Amazon will eventually drop you as a customer if you make it a regular thing to file returns.
There’s weird psychological aspects with this. People want to buy 5 star product.
I don’t know how well this translates to best buy, since they probably don’t have the same really large purchases skewing the average up, but I’m positive returns are a net positive for them using similar metrics.
I paid for college working at a big box store 20 hours a week in the 90s, about 50% of commissions were trolling the return line and selling to those folks.
For Amazon, I don’t think it’s that way… you mail them a return and they don’t cross-sell, many times they scrap and sell by the pound.
I remember even walking into a brick and mortar store, confused because I had no way to judge, for example, one rice cooker against another.
As the reliability of Amazon's reviews has waned, so has my loyalty.
If I'm just rolling the dice now, I might as well roll the dice on eBay or aliexpress.....
