Onnit currently features a sale offering up to 30% off on premium health and fitness products. This is the headline deal on the page and works across most shopping situations. Several other promotions are active at the same time, each suited to specific basket sizes and product types, so it's worth checking which will save you the most.
On smaller carts under $100. If you're buying a single item or a smaller order, check whether it falls within one of the featured deals first. The melatonin spray at $12.95 is a fixed price deal on a specific product, while the bestsellers starting from $23.29 offer entry points into Onnit's range at set prices. The up to 30% off sale may beat these fixed prices depending on the original cost of what you're buying, so compare the final price before you checkout.
On carts between $50 and $100. The up to 30% off sale should be your default choice here. If you are buying supplements specifically, the up to 25% off supplements deal may save more on some items, but the 30% sale is the safer bet across the full product range. If you are building a bundle from recommended combinations, the 20% off bundles offer applies instead, but this cannot be combined with other discounts, so you choose one or the other.
On orders over $100. You have two primary options. The up to 30% off sale applies across the site to selected products. Alternatively, free shipping kicks in at $100 spend, which saves you the standard shipping cost on top of your original price. Since free shipping and the percentage discounts are subject to different stacking restrictions, calculate the final price under each offer to see which leaves you better off. On a $120 order, for example, if the sale takes 30% off selected items you might save $36 down to $84, versus free shipping leaving you at $120 with only the delivery cost removed. The percentage discount nearly always wins at this spend level, but the math depends on your cart composition and the shipping cost Onnit would normally charge.
On supplement subscriptions. If you are setting up a recurring order, the 15% off subscription offer applies to those items specifically. This is lower than the up to 30% or up to 25% sale discounts, so you would only choose it if your subscription items do not qualify for the sale pricing.
Comparing your options. Once you have identified which offers apply to your specific cart, work out the final price under each one and pick the offer that leaves you paying the least. Remember that some offers, including the 20% off bundles, free shipping, and the fixed price deals, cannot be combined with percentage discounts, so you cannot stack them. Onnit's website will show you which products qualify for each discount, so verify your items are eligible before applying the code at checkout.
