1) you find a shop near you that sells cheap items or something you know you can sell online or perhaps even to another country that's more expensive
2) take your phone to that shop find the item you want to sell take a picture of all sides of the item/s note the price the shop is selling it at
3) once you've got your photos (for free) go home log into eBay create an advert using picture you just took, put a mark up of whatever you want work out the postage and put the advert up
4) when you get a buyer go back to the shop you took the picture from, buy the item, walk to the post office then post the item to the buyer who has already paid before you buy the stock so there is no risks except obviously if the buyer returns the item or says it wasnt delivered.
Anyway I found I had no returns and rarely did I get a difficult buyer maybe this is worth a think about? Let me know how you get on!
Hope you found this useful?
