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 Black Friday week mention, $4 off, and the lowest price we could find. This 8" tall border expands to 96".

Need more than one? It's also available in an 8-Pack for $27.99 with free shipping. That's $3.50 per barrier and the best price we could find for an 8-pack by $32.
