Walmart offers the Avery Round Removable Color Coding Labels 315-Pack, model no. 6733, for 98 cents. (Amazon has it for the same price.) Opt for in-store pickup to avoid the $5.99 shipping charge. That's pennies under our expired mention from five days ago and lowest price we've seen. (It's also the best deal we could find today by $2.) These 0.75" stickers come in neon green, orange, and pink.
