Well you got a USB cable with it ;-)
Drats, they also have that cheap USB thingeme on them.

Ok, you needed to re-program the boot loader. Rather than buying another
programmer, you could get a 2x3 to 2x3 pin header ribbon cable to link
two arduino's ISP headers, and load the programming sketch supplied with
the IDE onto your favourite spare 328P-based arduino and have a
programmer, after which you can re-use your arduino for the next
project. Hands up who does not have a spare arduino? There are detailed
instructions on the arduino website.
