The Shopping Radio is a 'harvestable' that was introduced during the Ratboy's Nightmare Update. It is one of the many collectibles that are needed by the players in order to complete the entries of the Itempedia of the Nightmare.
The Shopping Radio is rarely found in The Supermarket, although it is occasionally seen on the top of aisle shelves, on top of stacks of boxes, or tall, broken supports that can be seen throughout the zone.
In appearance, the Shopping Radio is a large radio composed of various metals and ornamentations. Two speakers can be seen in the front of the radio, a red speaker and a yellow speaker. A bar can be seen above the speaker, used to adjust the volume and switch on/off the radio. 'Antennas' can be seen at the top, as well as what appears to be a mechanism that can be turned by the user.
The Shopping Radio does not have any usages in-game that will benefit the players, other than to be sold to a selling vendor at a selling price of 15,000 gold.
