Bonus gift card terms

When to order

Place your order from up to, but not including, . Times are shown in UTC. Your order date determines eligibility; it can ship after the offer ends.

Discounts & bonus gift cards

  • Save up to 30% on select gear. Prices and discounts vary by product, edition and setup, subject to local stock.
  • Spend $500 and get $50; spend $700 and get $75; spend $1,000 and get $110.
  • Qualifying spend is the merchandise total after discounts, excluding taxes and shipping.
  • Each order receives one bonus gift card at the highest qualifying tier. Tiers do not stack, and separate orders cannot be combined.
  • The offer applies across markets. Thresholds are based on your checkout currency, and the gift card is issued in that same currency (currently USD). The numerical amounts stay the same; they are not converted from USD. For example, a GBP order of £700 earns a £75 gift card.
  • Your order must be paid in full and all items must be shipped before the bonus is emailed. Split shipments receive one card after the final shipment. No card is sent for a cancelled order or an order refunded before issuance.
  • The bonus is for a future purchase; it does not reduce the price of the qualifying order. Use it at checkout in the currency in which it was issued. The card has no expiry date, and unused balance remains available for later orders. Gift cards cannot be used to buy another gift card.

Shipping, returns & warranty

Boards marked 2026 carry a 5-year seam warranty: their seams are covered for 5 years, the rest of the board for 2. Junior boards, earlier editions, kayaks and accessories are excluded from this 5-year seam coverage.

Eligible products have a 30-day return window from delivery. Change-of-mind return shipping is paid by the customer. 2024 clearance boards accept returns for quality issues and do not include a board warranty.

Perfect!

I dropped one fin into the brine after a paddle, so I ordered two complete backup sets. Thurso shipped so fast I didn't miss my next paddle day. The best customer service! And the fins fit perfectly with my board.

Hopeful the new ones I just received dry out once locked in, would give an excellent reveiw if they stay locked in

Amazing customer service

Ordered 2 sets of fins not realising each had 2 fins already. A member of the team reached out to confirm how many I actually wanted and amended the order before it was sent out and also processed refund. Fins arrived quickly and are great quality. Big thanks to the Thurso team.

replacements

My husband lost his so I had to replace them. They feel like your going to break the lever when trying to snap them in. Most times they just don't lock in.

Great design

Easy to install and remove fins. Nice to remove them for transport as we have to deflate the boards to do so.

I lost a fin shredding the gnar in a shallow creek and this was an easy replacement! Thanks, Thurso!
