Just saw this today:

Basically this guy is trying to buy random stuff from TradeMe in New Zealand, and implemented a "bot" doing what's described in this xkcd comic.
- The bot gets $1 each day that it can save or spend
- It would then try to buy cheap items with free shipping from some specific categories
- If the bot can't find anything to buy, it would save the $1 so it has more fund the next day
At the end the owner of the bot gets random crap each single day delivered. Interesting concept with no practicality :)
What happens if it buys and sends you somthing illegal, can you blame the bot?
"but your Honor all that illegal horse porn was bought by my computer not me, it was the bot i tell you..the bot!!"
