e-bay...

... is a funny playground sometimes. I´ve been wanting to buy the Canon EOS 18-55 Lens that usually comes with the digital EOS-Cameras for some time, and have been watching the prices on ebay Germany from the 19th of December till the 14th of January.
Just for fun I turned most of the prices of the lenses I kept tabs on into an Excel-graphic (see above).
Of course there are differences in the state of the merchandise which justify a certain amount of variation, but the price seems to depend more on chance an on the time the auction ends than on anything else.

Btw: I got mine in perfect working order, and with an additional UV-filter, for 35,50 Euro (plus packaging) on a Monday noon.
Sometimes patience pay off literally:) .
