Sunmed is showing a 20% off new customer promo as the main offer on this page: the 20% off coupon code at the top is for first orders only and cannot be combined with other promotions, so it is best for new customers who want a straightforward percentage off their first online purchase. The code applies at checkout when you add your items to the cart and enter the promo at payment.
Small carts under $50 or single trial buys: If you plan to try one low cost item or the 5 item trial bundle, the Try 5 Bestsellers for $20 deal is probably the best value because it prices the five items at a fixed $20. The 20% new customer code cannot apply to a subscription or combine with other promotions, but it will take 20% off a single regular priced item. For a $40 cream, for example, the 20% code brings the price to $32; the Try 5 Bestsellers for $20 is cheaper only if the five items meet what you want.
Buying two items: The Buy 1 Get 1 40% Off sitewide deal applies automatically when you add two items to your cart, with the second item at 60% of its price. The 20% new customer code also applies to the whole order on first purchase but cannot be combined. For an example where items are the same price, two $60 items total $120. With the 20% new customer code that becomes $96 (20% percent off then final $96, you save $24). With Buy 1 Get 1 40% Off the total is also $96 (first $60, second $36), so savings tie at $24. If the second item is cheaper, the new customer code can save more. If the second item is much cheaper, calculate both totals and take the lower.
Buying a bundle: Some bundles carry a fixed reduction of up to $40 off. For a $150 bundle, the bundle discount reduces it to $110, which is less than the first order 20% price of $120, so the bundle wins. Bundles are pre selected and the $40 off applies only to those pages; the 20% code cannot be combined with that bundle discount.
Topical creams and subscriptions: If you plan to subscribe to topical creams, the Subscribe & Save 30% off topical creams or the 20% off subscription orders apply to subscriber purchases. For a $40 topical cream, subscribing at 30% off makes it $28, while the new customer 20% code on a one time order would make it $32, so subscribe if you want the lower recurring price.
OUR RECORDS: in the 12 months to October 2026 we listed 64 Sunmed offers (55 sales and deals, 7 codes). Percentage codes have typically been 20% off and the biggest code was 50% off in December 2025. Our team tested 7 checkout offers in the 12 months to October 2026.
When you decide, calculate the final cart total for the 20% new customer code and for the automatic deal you qualify for, and pick whichever leaves the lower total. Note the 20% new customer code cannot be combined with other promotions, so you must choose between it and any site automatic discount such as the bundle $40 off or the buy one get one 40% off.
