AOL posted an article this weekend about items that seem like a good deal at the $1 store but actually may cost you more, based on the unit price available at stores like Wal-Mart, Sam's Club, Costco and other warehouse stores. Another important point they make is that sometimes items at the deep discount stores pose potential health or safety risks.
Here's a partial list of items that aren't necessary a good deal at the dollar stores: batteries, bag candy, foam cups and plates, dishwashing liquid, sandwich bags, paper napkins, electrical products (holiday lights and extension cords), kid's jewelry and vitamins.
Some Items that are a true bargain: cloth napkins, plastic containers, arts and crafts supplies, gift wrap.
This is definitely a situation where a price book comes in handy! The bottom line in saving money is: it's all about the unit price! So before you head out to the dollar store, grab your price book and your calculator.
