Some people only buy a PSP because they only want to play a few games (I know I did) and later don't know what to do with it so they sell it. What if someone were to buy some PSPs in bulk and start renting them out? The person will rent the PSP for the same price it was bought at, and after a period of time return it to the owner who will return the money minus the rental. Any late charges will be duducted accordingly. Sounds like a good idea? Only problem is the starting capital.

Well, you could use a casing with a custom lock or seal it with a sticker stating that if casing is opened then there will be a penalty. Of course the penalty would have to be adjusted accordingly.

No no no, you rent at the same price as some form of insurance for the owner. Just like how you go to those book rental stores, you buy the book at the cost price and within a month the store will buy back from you after deducting the rental. This is to ensure that you don't run away with the book. The only problem now is determining who's responsibility is it if the PSP became faulty during the rental period.

Can I rent a girlfriend over there?
