What teachers do to save $$

So Staples has this deal where if they are selling a box of crayons for $2 and another store, like Target, has it for $1, Staples will charge you the cheaper price. Sooooo, Lorena, Shirley, and I decided to start our school supply shopping today at approx. 11:00 a.m. We went to Staples and discovered that we have to provide the store ads in order to get the discount so we drove over to Target to get their ad. We drive back to Staples and do our shopping. Not only did we have the Target ad but we also got the Office Depot catalog to refer to. We finally were ready to check out and by this time it was a little after noon. We had to do three separate transactions along with the discounts. We didn't leave Staples until 1:15 p.m.!! All this and we're not getting paid for our time.
