Pocketblocks are listed at random for .01 ETH. These listings are never announced and usually are up for 24 hours. This gives everyone an equal opportunity to grab ones they have been trying to collect.
Followers are given simple instructions to complete within a day or two. Winners are chosen at random from all who participate.

Sometimes related objects will be stealth listed together while still remaining at .01 ETH. By default the bundles filter is not selected so you will not see these listings without checking.
