EBay
People have to send what they sell themselves, usually using mail. Some items may be collected by the buyer such as items to large or heavy to post. Buyers can transfer the money in any way they want as long as the sellers accept payments made that way. A lot of people use PayPal to transfer the money. PayPal was owned by the same people as eBay until 2015. Margaret Whitman was the CEO of eBay from 1995 to 2008.
