Tent stakes make great stakes for yard decorations. The are more substantial than what comes with the decoration.This is more of "what amuses you"....
I was looking for replacement stakes for holiday yard inflatables. Typed "inflatable stakes" into Amazon, and instantly got a page full of results of what I was looking for.
Went to the Home Depot and Lowes websites to see if they might have some in actual stores that I could run and pick up tonight, and all that came up were actual inflatables.
I was amused that Amazon could figure out what I meant so much better than the other two.
