One product from minor line to top three
The 42L Flexi Tub 5-pack grew 331%, the largest single product gain on the account, and sold more than four times as many units. It is now one of the three biggest products the brand sells on Amazon, and it still carries the listing copy we wrote in January 2025.

Account revenue rose 15.2%, with units up 14.7%. Multipacks grew across the range: the 30-pack ground spikes up 52%, the medium propagator up 75%, the 20-pack up 33% and the grey 30-pack up 36%.
Three secondary lines, a three-piece snow shovel, a gravel tray 5-pack and a grow bag tray, grew 216% together.
