 You can use it for up to half of your purchase. So if you got $20 in mad money, you end up buying a tree for $50. You can use the full amount of the $20 towards a discount on your tree that might be on sale already. So if the product's already on sale that you want, say it's a rose bush or it's a fruit tree or our perennials are 25% off or we've got some great clearance items.
