Just got my monthly catalog and i saw it had the free shipping promo i mentioned last year, which i took advantage of and bought a bunch of 10 gallon pots. It doesn't show free shipping on their site, so they might not have updated it for the month of november - but this runs till end of year.

These are the pots i got last year and they are good quality for the price, obviously not the thickest stuff- but should last a few years without question.

AMLeo also has great prices on fertilizers (slow release/controlled release/water soluble), greenhouse supplies. They even have a poly remnant sale, not sure if that can be combined with free shipping though as those are bulk items.

I'm going to call up about poly remant sale sometime next week since i might get a great deal in combo with pots i need to get.

Bumping Matty's post from last November. I just received an email from A.M. Leonard giving free shipping thru 3/27/2017. Some good savings to be had by not paying for the shipping. Enter code 3D17P.

They're doing it again.  Free shipping, no minimum, expires April 3.  Promo Code 3G17P.

Thank you very much for posting the code. It is a good source pots.

If you're in the market for potting mix ingredients like perlite, vermiculite, rice hulls they've got the big bags.
