I purchased a poppit fidget toy on their website. 5 days later they sent me a fake USPS tracking number in a Fedex format, and they asked me to use 17track.net to track the package. Even 17track couldn't identify the courier of the package much less track it. So the tracking number was FAKE.
That's when I discovered the company isn't actually in California but is a Chinese scam site. Thankfully I paid via Paypal and am in the process of filing a claim.
