"You are wrong. I bought by AliExpress by credit card and had full protection. So is clear that you’re trying to scam people."

Excuse me, I never said that AliExpress does not offer buyer protection, I said that they don't offer escrow. You still have to pay 100 % upfront obviously.

Furthermore:

1. AliExpress is having enormous difficulty weeding out fake goods right now. Go to the CDC warning page showing the most prominent types of counterfeit particulate respirators and then go to AliExpress and compare. You will see a lot of them there.

2. The Korean government has issued several warnings against procuring fake masks via AliExpress, etc.

Your aim here is to buy large quantities of masks, sell them at a >200 % profit and make money. Right?

Your aim is not to spend 3 weeks fighting with AliExpress and your credit card company in order to get a refund.
