Walmart offers the Bird-X Irri-Tape Bird Repeller 100-Foot Ribbon for $8.43. Choose in-store pickup to dodge the $5.99 shipping fee. (Amazon charges the same price with free shipping via Prime or Subscribe & Save; Home Depot has it for a few cents more via pickup.) That's tied with our mention from two weeks ago and the lowest price we could find by $2. It repels birds with 3D shapes and colors, and covers up to 4,000 square feet.

Update: It's now sold out at Walmart; however, it's still available at Amazon with free shipping for Prime members and Home Depot for pickup at the same price.
