Where are you?
I have about 50 quart or gallon size ones you can pick up in Dacula.
It's left over from my bright idea of planting stuff during July in Ga.

I buy my plastic pots super cheap in bulk from the folks that run plasticflowerpots.net - NOTE: they sell them cheaper on eBay than what you'll find at their site, I usually end up paying around 25¢/pot for 1gal pots in lots of 50, and they will combine shipping on multiple orders. I find this to be much more economical than spending the time and gas to drive around and find used ones, of which you never know the quality until you make it there and see them.

Same nursery grade pots you'll find anywhere.

Daddy's we can't email you either, your email isn't open and available. Nursery pots tend to be fairly easy to get around here.
Please post where you are located and wanting to pick up and what sizes you need. We might could have them for you!
