Electronic Mall Madness (1990)

From the box:

Attention Mall Shoppers! The voice of the Mall has big news! Come inside and hear all about the giant sales and special bargains! Then join your friends on a wild shopping spree as you rush from store to store!

Press the console button and the Voice will tell you where to move and where to find the best sales. Hurry! Your friends may try to beat you to the bargains! See if you can be the first to buy six items. IF you need more money, make a quick stop at the bank!

To buy or bank - just insert your credit card into the slot and listen. You never know what the Voice of the Mall has "in store" for you!

I wrote in my research notes 1993:
A 3D shopping arcade is assembled and the players (the designers obviously think that only females go shopping) must wander round the board looking for bargains at the sales. It has a hilarious (not intentional) talking gadget which announces where the sales are.
