All our products (except special order products) have a One Full Year Guarantee. The only requirement is that the returned product is at least 70% full when received back at our warehouse.

Special Order Products - Special Order Products are non-refundable.

Unlike Other Companies there is no small text:

• We don't make you jump through hoops.  Just follow our Easy Return Directions
• We don't make you keep the receipt to get a refund
• We don't only give you 30 or 45 days to try the product

Why is our warranty so complete?  First, our products are second to none, and we have very few products returned.  Second, we want you to feel confident enough to plan ahead and stock up with several cartridges. You should never have to worry that if you open up a cartridge six months later and it doesn't work, that you are out your investment.

Return Shipping Costs - If the product we ship is defective, or if we ship a product other than was ordered, we pay the shipping cost to return the product. Otherwise, the customer pays the shipping costs to return the product.
