Amazon offers the BlueMagic 900 Carpet Stain & Spot Lifter 22-oz. Can for $3.88. Add it to your cart via Subscribe & Save and it drops to $3.30. With free shipping, that's tied with our mention from August as the lowest price we've seen. (It's about a buck under what you'd pay in local stores.)

Be sure to cancel Subscribe & Save after your order ships or you'll be billed for subsequent shipments.
