YSAK 30: Buy the grass, get the weed

A shy reader sends this huh? from Stratford Ontario:

Grass clippings several bags
Price: $1.00
Address: Stratford, ON

One dollar per bag you want it come get it i have several bags of grass clippings.
No questions asked they're yours.
Will deliver.

I'll mention that I'll likely be giving away a giant pile of dirt with a similar ad. Mind you, that's because the dirt is chock ablock with goutweed, dandelions and other things any self-respecting homeowner would not want in his or her yard. But, have at it, fill your boots.
