Spring Hill Nurseries is once again offering $20 off a purchase of $20 or more. Just use coupon code 414217 at checkout to get the discount. This coupon works on liquidation items, as well as regularly-priced items.
Shipping is not included in the discount and starts at $7.95. However, you should still be able to get a pretty good deal with the $20 off coupon code.
Thanks, Christian Clippers!
