One of the deals at Toys R Us this week are the 24 ct. Crayola Crayons for 4 for $1, making them just $.25. You need to buy 4 of them to get the price though.
You can always take the ad to your local Walmart or Target to price-match.
I love to buy up Crayons when they are at a low price as I use them for party favors for my kids birthday parties. I can often find coloring books at a low price and the kids love getting them each year. I sometimes use them to make a cute art/crafty gift basket for friends’ kids, too.
