Lotion bottles have been known to leave behind almost a quarter of the product when the container appears to be empty. To squeeze out every last bit, Make It Or Fix It Yourself attaches a little tube to the end of the pump.
It's best to first check the size of the pump you use and buy tubing accordingly because it should be a snug fit to work well. Snip off a small piece of the tube -- enough to fit comfortable at the bottom of the bottle. Make sure your pump is empty and then attach the tube to the pump.
Whenever the pumping stops, just remove the pump and adjust it so that the tube attachment faces the other way in the container to make sure that it removes as much of the lotion at bottom of container as possible. This little tip will help to not waste money and lotion by throwing away the lotion before it's completely emptied.
The link below has step-by-step instructions with photos, and an example of the kind of $US3 tubing you will need, so you might want to check it out before you try this out for yourself.
