Aren't those price tag stickers annoying? Here is the best way to get them off of any purchases you might have made.
Soak a paper towel with water.
Rub the towel on the sticker until the sticker is very moist.
Take a butter knife, or other dull utensil, and rub it back and forth on the sticker.
If there are any sticker remnants left, wet another paper towel and repeat the process.
When you can no longer discern where the sticker was (either by sight or touch), then you are finished.
