be careful of scammer ebay does not accept bitcoin and if anybody tell you that he/she is selling BTC on ebay I will advice you to buy from exchanger website instead of taking a risk of buy BTC on ebay. it is not safe
You have ebay buyers protection if you dont get what you want so there is little risk to buying i see. The bigger risk comes from selling on ebay. My tips for buying on ebay though if you do/can:
1.)Use ebay case system if you do not get what you paid for
2.)Use paypal cases as a back up if needed.
3.)Pay via card and not your paypal balance so you can do a bank chargeback if needed.
4.)Buy in small amounts, there is no reason to buy a large amount in 1 go, i dont believe it could be cheaper this way else the seller is maybe a scammer - not that they can really scam you anyway if you follow rules 1 -3, it just means your time wasted is at risk.
But yeah all in all i might actually buy small amounts of bitcoin on ebay if possible tbh. Dont see why not. Depends on price more than anything.
