Remember that the word colmado actually means full or full to the brim. We used to own a colmado and I couldn't understand why we had to have it overflowing with stock - 100 tins of Carnation, 100 bottles of Brugal, until it was explained to me that people don't buy in a colmado unless it is full. Hence the reason for lots of out of date products.
