Sears offers the Arnold Utility Cargo Carrier for Lawn Mowers, model no. 490-850-0015, for $2.97. Choose in-store pickup to dodge the $5.99 shipping charge. That's tied with last week's mention as the best price we've seen for this carrier. (It's also a current low by $7.) It features adjustable, non-slip straps and a storage area for a drink, cell phone, and small hand tools.

Update: It's now available for in-store pickup only.
