the yardsale of the Internet

A site where one may bid on auctions for almost any item imaginable, (not just useless trinkets, as implied by the other definitions here), with the allure coming from the incredibly cheap prices of nearly everything that gets listed. Often, it is possible to find items listed at half their retail price. Granted, shipping costs are usually high, but an extra $5 on shipping doesn't overshadow paying $300 for a new graphics card that's being sold for $400+ everywhere else.

eBay is like life itself; there is a vast array of choices to suit every possible taste and desire, from furniture to video games, to electronics, to books and trinkets.

Fraud is generally not a problem, since there are thousands of well-known and trustworthy sellers, easily identifiable by their feedback records.

In the book City of Bones from The Mortal Instruments series, Clary calls ebay "A mythical place of great magical power."

The only place where you can sell your soul and get $20 for it.

A place where you can find almost anything (whether inedible or not) to bid on. Human body parts have been sold at over 500 dollars. Bought by tin.
