Home Depot has six (6) Ryobi Expand-it attachments (see images) on sale when purchased together with ONE+ HP 18V Brushless 15 in. String Trimmer with 6.0 Ah Battery and Charger

Discount on the attachments varies but equals about 20% off or more. In my example, the Edger (RYEDG/Store SKU #1010524103) ended up $ 58.74 (versus $ 79).
For a best deal, return unopened Trimmer.
