Shop Dubby & get 10% off or use code AdventureDen at checkout

⚑ What you get from us

3 months of Premium: unlimited tool uses (no 5-per-day cap), no 24-hour security check, no ads, and priority processing β€” on up to 5 devices.

πŸ₯€ What you get from Dubby

10% off off your order with our code, plus zero sugar, no artificial colours, and coffee-fruit extract with vitamins and amino acids for focus.

🎁 What counts

Any completed Dubby order placed through our link or with our code β€” tubs, sampler packs, shakers, bottles or merch. There's no minimum spend.

How to claim your 3 months

  1. Order through our link or code. This link applies the discount automatically. If you'd rather shop from the Dubby site directly, enter AdventureDen at checkout β€” that's how the order gets matched to you.
  2. Complete the purchase. Wait for Dubby's order confirmation email.
  3. Send us proof of purchase. Open the πŸ’¬ Feedback widget in the bottom-right corner, choose Dubby order β€” claim 3 months Premium, attach a screenshot of your order confirmation or receipt, and give us the email address you want the key sent to.
  4. Get your key by email. We check the order against our affiliate dashboard and email your Premium key β€” usually within 48 hours. Paste it into Activate key manually (or the key page) and Premium switches on for 3 months.

The fine print

  • One Premium reward per person per order. Multiple orders don't stack beyond 3 months at a time β€” a new order extends your access when the current period ends.
  • The order must be placed through our affiliate link or with code AdventureDen and must appear as a completed order in our affiliate dashboard. Orders that are cancelled, refunded or charged back don't qualify, and a key already issued for such an order may be revoked.
  • Proof of purchase means a screenshot or PDF of the Dubby order confirmation showing the order number and date. We only use it to match the order and delete it once the claim is settled.
  • Keys are delivered by email, so give an address you can receive mail at and check your spam/promotions folder. Lost keys can be re-sent from the key recovery page.
  • Premium terms are otherwise unchanged β€” see the Terms of Service. This offer can be withdrawn at any time; claims for orders placed before withdrawal are still honoured.
  • PdfStuffAI is a Dubby Energy affiliate and earns a commission on orders placed through the link and code above. We are not affiliated with, or acting on behalf of, Dubby Energy in any other way, and Dubby's own terms, shipping and returns policies apply to your order.
