Removing price tags

Too easy, Just heat them first with a lighter, a few cm's away. It will peel as butter

There is also a spray you can find at most Automotive stores like Auto Zone called (Sticker Shock).  It's designed to take off bumper stickers.  It works beautifully on all those types of impossible sticky glues used for Lables and price tags... I always keep a can of it under my sink.  It works on everything, like glass, plastic, tin, you name it, the glue literally melts right off!  You gotta try it.

Note: Don't use this stuff on Clothes or Fabric!!!

try using a little rubbing alchohol or some WD40.  They usually soften the sticky gum base on the back of those nasty price stickers.  Of course, always check a small corner of anything to make sure its not going to ruin it.  Also I heard Vodka also works.
