The My Soil page is currently showing an Extra 20% Off Selected Items as the lead deal, and that is best if you are buying one of the selected items on the extra discount list. You save 20% on those selected products at checkout, so this is the go to when the items you want are included. The page also lists sale pricing that is up to 30% off, plus smaller percentage offers on specific product groups like soil test kits, OMRI organic fertilizers, Starter Pack and Pro Pack.
If you are buying a selected item that carries the extra 20% off. Use the Extra 20% Off Selected Items offer. On a $100 selected product, the 20% discount takes $20 off, so you pay $80 and save $20. This is the one to use when the item page or cart shows it as a selected product covered by the extra 20% off.
If the item you want is already in the sale and shows a larger markdown. Use the Up to 30% Off Sale Products price when the product page or cart reflects that sale level. For example, if a sale price is 30% off a $100 product, the price becomes $70 and you save $30, which is better than the 20% result. Remember that "up to 30% off" means not every sale item will be 30% off, so confirm the sale percent shown on the product page.
If you are buying a soil test kit, OMRI fertilizer, Starter Pack or Pro Pack. Use the specific product offer that applies: 9% off a soil test kit, 8% off OMRI organic fertilizers, 7% off a Starter Pack and 5% off the Pro Pack. For a $50 soil test kit, 9% off reduces the price to $45.50, saving $4.50. These product specific discounts apply only to the listed product ranges.
If you are a first time visitor with a very small basket. Signing up to the newsletter may expose special offers and promotions, but the signup itself is the only listed signup option and is not the lead deal. Use the newsletter if you want promotional emails, but rely on the visible product discounts for immediate savings.
Our records show 13 offers listed for My Soil in the 12 months to October 2026, and the biggest percentage we have seen in that period is up to 30% off. Our records do not list any team checkout tests for My Soil in that 12 month window, so there are no tested code results to report.
When choosing between the options that apply to your cart, calculate the final total for the same items under each applicable offer and take whichever leaves the lower total. There is no site term here that says these offers combine, so treat each discount on its own and use the single offer that gives the lowest final price.
