Just popped into my local Tesco (Highwoods, Colchester) and whilst there picked up a new version of the MB Operation for just £3.16 !! Was £12.99. saving £9.83
The new version has flushing toilet sound, woof of a dog, sneeze sounds, dripping sound, door bell, mobile beeps, burrping sounds too. Yet still has the red nose...
Highwoods had loads in their bargain aisle, about half an hour ago.
Not sure if this is online too, or when this was reduced... on a when its gone it's gone basis I reckon.
