A year ago, IKEA began an experiment to wean itself from the use of plastic bags....The deal was this: customers could bring in their own reusable bags, buy a huge, reusable plastic sack from IKEA for 59 cents, or pay five cents for each plastic bag. All proceeds from the regular plastic bag purchase would go to American Forests for tree-planting.  IKEA now reports that its "bag the plastic bag" program was a huge success, with more than 92 percent of their customers opting for one of the reusable choices.
