I more or less stopped completely. I spent nearly $10,000 on Amazon in 2016 (Multiple computers, clothes, games, foodstuffs - Just everything); It was down to $2000 by 2018 after I stopped trusting it for anything but big-ticket items that were unlikely to be counterfeit. It picked up again in the pandemic, but after a series of bad purchases in 2023 I've spent less than $1000 in the last year, and over half of that is a CPU that I really feared buying because of fraud/counterfeit concerns, and immediately inspected and installed to assuage those fears.
