I always watched for the loss leaders for oldest DD's kids, since those along the Wasatch Front are MUCH better than the ones in the Uintah Basin, probably because there are so many more shoppers to fight over, but this year I ran into a combo to pass on to you all for next year.
Office Max has a "rebate" type card call MaxPerks. When I return an empty HP ink cartridge, they credit me $3 to my "card". I can't use it right then, I have to wait for it to "post" a few weeks later. The "credit" expires after 3 monhts of not used. Think of it as their job to get the cartridges & design a cumbersome program so most people won't use it. MY job is to make sure I use the credits. The cartridges can sit in their cute little packages until a month or so before we need the credit, at which point they get turned in.
Nevertheless, oldest DD & I have diligently been "depositing" the ink cartridges, & I just bought 6 ten packs of pencils for a dime each (limit of 6), 6 of those composition books for 50 cents each, 3 wooden rulers for a penny and 6 two-pocket folders for one penny. Bottom line; they cost us NOTHING, & I still have a couple of dollars on the card! Check it out, & use it next year!
