Target offers the Crayola 64-Count Crayons, model no. 52-0064, for $2.99. (Staples charges the same with free shipping for Staples Rewards members.) Opt for in-store pickup to avoid the $5.49 shipping charge. That's tied with our mention from two weeks ago and the lowest price we could find now by $3, excluding the below mention. It includes a built-in sharpener.
A close price: Toys 'R' Us offers them for $3.19 via in-store pickup.
