Fin Fun's headline offer is the 15% off discount code, which works in physical stores and gives you the brand's deepest code-based discount. For online shopping and different basket sizes, several other discounts compete—including sale pricing up to 70% off, fixed product deals, and a free shipping threshold—so your best saving depends on what you're buying.
Shopping in Fin Fun stores: The 15% off voucher code is your best bet, applying to your entire purchase at any checkout. If you're buying full price items, this code saves more than the 10% off alternatives also listed for in-store use.
Buying online at regular prices: The featured 15% off code does not work online, so you'll choose between the 10% off sitewide codes or the free shipping offer if your basket qualifies. Any regular priced item at $100 or more gets free shipping, which is worth calculating against 10% off depending on your order total. On a $50 purchase, 10% off ($5) beats free shipping since you haven't hit the threshold. On a $120 order, free shipping saves you the delivery fee while 10% off saves $12, so the percentage discount still wins. On a $200 purchase, 10% off saves $20, which again beats most standard shipping costs.
Buying Fin Fun sale items: The End of Summer Sale cuts up to 70% off selected sale styles through 30 September 2026—this typically beats any code discount. The same applies to the 50% off factory seconds deals if you're shopping for discounted Riptide or Atlantis tails and other items marked as factory quality. The 25% off blankets sale applies only to that category, so check whether blankets are on your shopping list.
Buying specific products: Fin Fun lists several fixed price deals: the Asian Magenta Mermaid Tail at $39.95, the Riptide Atlantis Tail for $59.95, the Purple Fantasy Starter Tail at $44.95, and matching swimwear sets starting at $24.95. These are priced items rather than discounts, so compare them directly to the listed prices before applying any percentage code.
First time shopping: If you have not shopped with Fin Fun before, signing up to the newsletter may unlock further special offers and promotions, though none are detailed here.
At checkout, you can use only one offer per order, so compare what's available in your basket and apply whichever option saves you the most money. Sale prices and fixed product deals usually outperform percentage codes, but if you're buying full price items and shopping in store, the 15% off code will give you the biggest saving.
