eBay

Can anyone tell me, if eBay is charging final value on your listed price, even though you sell it for less with offer, how does this affect my taxes/income? If I list an item for $100 and take an offer for $80, I am charged final value fee on the $10...

It seems over the last couple of weeks I have had a rash of "Offers" that I have accepted and never hear from buyer/get paid. After reviewing these Offers I am finding that either the person has been a member since 2016 (etc) and no current feedback/...
