2. “The world’s online marketplace” 88 million active users Over one billion page views per day Started in 1995 by programmer Pierre Omidyar of Echo Bay Technologies First sale was a broken laser pointer Now over 15,000 employees Annual revenue $7.7 billion

3. Millions of items sold daily Collectibles, appliances, automobiles, services….you name it Used by individuals and businesses, including some of the largest corporations It’s a world-wide marketplace

4. How does it work? Auction-style listings Fixed-price listings Fixed-price with “best offer” Sellers pay a listing fee + 1.5% of the selling price No fee for buyers Buyers and sellers rarely meet in person

5. Auction listings Uses “proxy bidding” − eBay bids for you up to your maximum bid The winner pays the second highest bid amount plus one bid incement

6. Example: Richard sells his DSL modem I take digital photos of the modem I compose a description – − Model # − Condition (any damage or problems) − New or used? − Original packaging and manuals? I decide to use an action with “buy it now” option

7. Example: Richard sells his DSL modem (cont’d) I decide on a starting bid of $4.95 − Low starting bid encourages bidding and keeps listing fee low − I know the modem will sell for more I decide on a “Buy it now” price of $49.95 − …after looking at “completed listings” for similar items I decide on a one-week auction period

8. Example: Richard sells his DSL modem I decide on a flat shipping charge of $9 for Priority Mail shipping I decide to only accept PayPal payments I login to eBay and post the auction I obsessively look for bids

9. Example: Richard sells his DSL modem I decide on a flat shipping charge of $9 for Priority Mail shipping I decide to only accept PayPal payments I login to eBay and post the auction I obsessively look for bids

10. Example: Richard sells his DSL modem -- bidding First day – Joe bids $5 (If no one else bids, he’d get it for $4.95) Second day – Mary bids $8 (If no one else bids, she’d get it for $5.50) Third day – Mike bids $20 (eBay has now raised the minimum bid to $8.50) Jane bids $10, but eBay automatically enters a bid of $10.50 for Mike – he’s still the high bidder

11. Example: Richard sells his DSL modem -- bidding Last day – Eric bids $40 (eBay bids $20.50 for him) Joe comes back and raises his bid to $45 Auction time expires and Joe wins at $40.50 I use the eBay site to send an invoice to Joe for $49.50 Joe sends a electronic PayPal payment

12. Example: Richard sells his DSL modem -- bidding I pack the item and ship it to Joe I use PayPal to generate a printable paid shipping label I drop the package at the post office Joe leaves positive feedback after receipt I leave positive feedback for Joe

13. PayPal Provides a secure and convenient means of transferring money for eBay purchase – or anything else Started in 1999 as X.com Works much like a checking account Not legally classified as a bank Accounts can send and receive payments Accounts can use a backup credit card Similar to an escrow service

14. PayPal Allows sending money to anyone with an e-mail address Receiving party is charged 2.9% + $.30 Sender is not charged a fee Money can be withdrawn to a bank account or credit card account electronically

15. eBay tips Your bid is a contract to buy Know what you’re bidding on If you’re not sure, e-mail the seller Check feedback scores and comments Watch out for high shipping charges Don’t get caught up in bidding wars Use a sniping service such as www.justsnipe.com

16. Buying and selling safely eBay fraud is extremely widespread You can protect yourself by following some simple rules: − If it sounds too good to be true, it probably is − Only pay using PayPal or credit card − Only accept PayPal payments − Only ship to a confirmed PayPal address − Use signature confirmation for large purchases

17. Buying and selling safely − NEVER send cash or a Western Union payment – anyone who demands that is a scammer − In case of a problem, use PayPal’s resolution service − Contact eBay’s security department
