Preprinted stickers are a godsend. Rather than handwriting your address on every bill, simply slap on a return address label. (At American Stationery, you can get 250 for just $10, or 4 cents apiece.) When you’re racing out the door for a birthday party, don’t bother to stop and write a card. Just attach a personalized gift sticker that reads, “Happy Birthday! Love, Lauren.” (Tiny Prints sells sets of 24 for $7, which means they’re about 35 cents each, far less than a greeting card.) And Label Daddy has dishwasher-safe, washing machine-proof stickers for lunchboxes, backpacks, clothing, shoes, sports equipment, water bottles and more.
