Kosterina's headline offer is up to 12% off when you commit to a subscription, but the brand also runs strong one-time purchase deals for shoppers who'd rather buy outright. Your best savings depend on your basket size and whether you're interested in ongoing deliveries or a single order.
Signing up for a subscription: The subscription option delivers up to 12% off, making it the cheapest route if you're happy to receive products regularly. This works well for customers who use Kosterina's oils consistently and want long-term savings.
First-time shoppers buying once: If you're new to the brand and want to try their products without committing to a subscription, take the 10% off your first order. This gives you a meaningful discount on any basket size for a single purchase.
Buying one of the featured sets: Kosterina's bundled sets offer excellent value for specific product combinations. The Greek Taverna Set is priced at $62, while the Dipping Duo Gift Set comes to $55—both are complete ready-to-gift or keep options. The Extra Virgin Starter Set also qualifies for 10% off on its own. Compare these fixed prices against what you'd pay for the same products separately, then apply any applicable percentage discount to see which route saves you more.
Larger baskets: If you're spending above the set prices and building a custom order, the 10% first-time offer or the subscription's up-to-12% discount will likely beat the fixed-price bundles. Work out the numbers in your basket at checkout: calculate 10% of your subtotal, then compare it against the set prices to see which gives the larger saving.
Remember that you can only use one offer at checkout, so compare your available options before you finalize your order. Check which deal produces the biggest discount for your specific basket, then apply that one.
