A phrase referring to the dubiously exciting activity of moving forward stock in high unit-sale shops (such as supermarkets) to the front of the shelf so that the customer is more likely to buy it.
Pulling forward can quickly drive you out of your mind, so I recommend doing it with someone else to talk to.
Some shops are also fanatic about date rotation, which is making sure that products soon to go out of date are near the front, and this can be done the same time as pulling forward.
