A neat bot would be one which automatically buys and then resells things with a markup. It would figure out the usual price an item goes for on a website like Ebay, and purchase it if the price is set far enough below.

A classic case of arbitrage. But it seems to me that it would be quite hard to achieve on ebay. You need to have very little overhead, mailing stuff isn't usually that cheap. Drop shipping --send things directly from seller to buyer-- is allowed on ebay but has many restrictions.

It would be very interesting to see if you could get some heuristics that choose products that are at least moderately useful instead of screen protectors and (exploding) batteries for various mobile phones.

Especially if you delay sending the seller a postal address long enough to find a buyer.

The mailing/shipping could be handled by Amazon: http://www.amazon.com/gp/seller/fba/fulfillment-by-amazon.ht...
