Mall Maniacs is an advertising tie-in shopping game with four game modes: The main game mode (where you need to buy all the groceries marked on your list before your opponents), random mode (where you're randomly introduced to a grocery you must find), a quiz mode (you must answer questions about groceries in order to pick them up) and the shopping cart race.
You can choose from ten characters, each with their own stats to enter the race for groceries in five levels: Mini Market, Jungle, Oriental, Aqua and the Future.
The game also supports network play. [source:mobygames]
This game was released in Sweden and Finland as free of charge for one day, then it become retail, don't know about the U.S. version, just know that could get at Pamida stores.
Some days ago discovered that they(SWE and FIN versions) become freeware, so now we can play this awesome game that mixes racing and shopping elements all in one, too bad the companies gone bankrupt.
