Suspiciously priced items from external websites advertised on TikTok

Has anyone actually bought these? All of the comments on these videos look fake and I can NEVER find anything negative or mentioning the quality… I get them all the time because the clothing is cool but I don’t trust them at all. The shoes in the last picture claim to be original sketchers brand shoes which sell for like 70-90 dollars online depending on where you buy them.. but this website sells them for 29 dollars plus like 10 dollar shipping. It’s kind of concerning to me since it feels like they’re advertising potentially bad quality products but they usually have zero places to find reviews or comments on the ad about the quality
