Despite being a computer nerd, I know NOTHING about Ebay. I signed up for an account today (a buyer's account, and since I may from time to time want to sell something, a seller's account as well) My question is this...from what I understand, the buyer's account is totally free. Am I charged anything on my seller's account if I don't post anything for sale? Let's say I buy things, but don't sell anything, just using my seller's account "in case I decide to sell something"...I don't want to be charged for something I don't use. Can someone give me a quick overview?
