Questions about Ebay n Paypal?

I buy and sell on ebay all the time and they have made it very tough on sellers. If the buyer has a problem with your item or outright lies about it Paypal will freeze your account until it is settled. I knew a seller who sold some mint dolls and the buyer lied and said they were trash and she was returning them. As soon as she mailed the "dolls" back Paypal took the money out of the sellers account and refunded the "buyer" The seller received a box of rocks...no "dolls". So she was out the money and the dolls. My best advice is open a whole new account that is not connected to your main banking account and remove the money the minute you are paid. Especially if it is a high dollar item.
On a happier note , this rarely happens and most transactions are smooth and pleasant.

you ought to use your paypal account as long because it has money in it with the aid of fact as quickly as you "win" something off of ebay, if paying by potential of paypal it is going to ask to your paypal e mail handle and the money will immediately come out and be deposited into the sellers account.

"But now I have sum second hands clothing that I would like to sell."
You might want to consider a yard sale or Craiglist; no fees and cash & carry there. Clothes don't move well on eBay except gently used designer name brands offered by well established sellers.

"do I need to do any procedures to be a seller n buyer as well?"
To be a seller, you do have to create a sellers account and Verify your Identity

"Should I change my Paypal account from domestic to business?"
You will be changing your Personal PayPal account to a Premier one so you can receive money.
