"There are 24 days in December before Christmas EVERY year. Make the most of those days because they are the days that count the most."
With that said, you only have a couple days left to check your inventory to make sure you have what you need to make the most of those days.
To borrow another cliche, strike while the iron is hot.
As much as you might be needed on the sales floor this weekend, take some time to check your inventory for fast movers and hot products. Make a list of the top ten items you are seeing fly off the shelf. Prioritize that list and start emailing/calling your reps right away. Get those hot movers on order and back on your shelves as soon as possible.
Don't worry about making great terms, worry about getting the products that will make your customers smile. That is your goal this time of year.
Should you still be ordering? Yes! Get the hot stuff in now. Don't worry about the rest.
PS The goal all year long should be to make your customers smile, but this time of year, with the increase in customers, it becomes twice as critical. Make your customers smile now and you will smile in January.
