Random item sets are generated each time the Tamagotchi visits. Each set includes 4-5 items, all from the same category. The currency accepted in all shops is Tamagotchi Points, which are gained by playing minigames, opening letters or using a cheat code.
Sometimes when watching the shopping channel on later versions, the TV screen might have small squiggly lines on it, like a blur. Then another picture will show up, with a penguin-looking creature standing next to a sign saying FAIR. It resmbles the host of the regular shopping channel, just with different features. Whether or not the itenms are more special or different than the other channel's items cannot be determined.
