What can you buy on TikTok?

English isn’t my first language so I apologize for any mistakes.
I asked this on r/nostupidquestions but I think this might be a better place to ask?
This is probably a really weird question to ask, but what can you buy on TikTok that always cost $52.00, $104.00, $310.25, $312.00, or very similar money?
It always shows up as Purchase TikTok TikTok.com DE on the card app.
