With orders of $25 or more, Amazon offers Prime members the Fiskars Composite Trowel, model no. 7978, for 84 cents with free shipping. (Non-members can spend $35 or more to qualify for free shipping.) That's tied with yesterday's mention, since expired, and the lowest total price we could find by $4. It features nylon/fiberglass composite construction.

Note: This item is part of Amazon's "Add-on program" and can only be purchased with an order of $25 or more.
