Improved Meyer alert - Loews
Not sure who has Loews, or if this special exists outside of Seattle, but currently they are selling IML's for $14.98.
The supplier is Duarte, and the ones I saw looked relatively healthy - although pleading for some good drainage. I bought four (!) so I can do some experimentation on what works best up here. I plan to try two different mixes and clay vs. plastic pots. I'll let you know if I discover anything interesting :)
