Home Depot offers the Backyard X-Scapes Expandable Bamboo Border, model no. HDD-BT02-1, for $4.50. Opt for in-store pickup to avoid the $5.99 shipping charge. That's tied with our mention from three weeks ago, $4 off, and the lowest price we've seen for a single unit. This 8" tall border expands to 96".

Need more than one? It's also available in an 8-Pack, model no. HDD-BT02, for $27.99 with free shipping. At $3.50 per barrier, that's also tied with our mention from three weeks ago, a current low by $32, and the best per-unit price we've seen. Both deals end April 30.
