[N-Ext] Build-a-Box | 4 Gallon - Build to Save

!!PLEASE MAKE YOUR SELECTION WISELY. ONCE YOUR ORDER IS PLACED PRODUCTS CANNOT BE EDITED, MODIFIED, or SWAPPED!!

**SAVE 20% off individual retail prices when you buy 4 gallons in a Build-a-Box. Mix-n-Match any combination of 4 gallons. When you combine 4 gallons we save on shipping and fulfillment and are passing that 20% saving over retail prices directly to you!**

This combo pack is a customizable mix-and-match. Build your own box of N-Ext Fertilizer products.

Mix and match 4 - 1 gallons

The idea is for you to make your own custom bio-stimulant strategies, but also offer you flexibility should you only need to refill certain products. You also save 20% off the retail gallon price when you create a Build-a-Box. 

Having this kind of flexibility to order Greene County products really allows you to optimize your strategy for the greenest, healthiest lawn on the block.
