Chapter 10: eBay.com eBay is the largest online auction site. Sellers pay a small fee to list their items, which can be sold at a fixed price or auctioned. Generally, the auction lasts several days, and the bidders submit electronics bids. After the auction closes, the highest bidder receives an email and gets three business days to contact the seller. eBay provides ratings on buyers and sellers based on their positive and negative comments. eBay has set up policies to guard against 'feedback manipulation' and 'feedback abuse.' eBay encouraged buyers to pay through 'PayPal' and 'PayPal' provides $2000 free insurance in case the buyer doesn't receive the product or the quality of the product is poorer than expected. eBay's safety staff investigates alleged misuses at eBay, such as fraud, trading offenses, and illegally listed items.
