The advertisment (advertisement) is a form that appears in the player's mail box in Kesselinperä after about two hours of real time. It is used to order the mikropekka computer. Clicking on the form will cause an envelope to spawn, which has to be taken to the post box at Teimo's Shop.

The order works in the same way as parts ordered from the parts catalog; the payment happens once the order arrives at the shop, after which it will appear in a cardboard box on the loading dock. The box contains four parts for the computer: the case, monitor, keyboard & mouse, and speakers.
