Probulin's Goodbye Summer Sale runs through September 8, 2026, with automatic discounts applied at checkout based on your basket size. The headline offer gives you 30% off plus a free gift when you spend $75 or more, making it ideal for anyone building a standard supplement order. Larger baskets unlock an even bigger saving, so read on to find which deal works best for your shopping plans.
Spending $50 to $74: If your basket lands in this range, grab the 25% off discount with no minimum code needed. That's the best saving available at this spend level and applies automatically at checkout.
Spending $75 to $99: You'll qualify for the 30% off plus free gift offer, which beats the lower tier and rewards you with an extra incentive. This is a strong saving that also works on one-time purchases.
Spending $100 or more: The 35% off plus free gift deal becomes your best option. The extra 5 percentage points on top of the $75 tier discount means your saving grows with your basket—for example, a $100 order saves you $35 instead of $30.
Setting up a subscription: If you're ready to commit to regular orders rather than a one-time purchase, the subscription discount offers 15% off. Subscriptions sit outside the Goodbye Summer Sale, so you'll choose between the recurring 15% saving or the sale's higher discounts on a one-off purchase. Most shoppers will find more value in a larger one-time basket to hit the sale's higher tiers.
Signing up to the newsletter: New visitors can join the newsletter for special offers and future promotions, though the current Goodbye Summer Sale offers are already available without signing up.
Only one discount applies per order, so you'll want to compare your final basket total and claim whichever saving produces the biggest discount. The sale tiers all stack with Probulin Total Care Club points if you're a member, but you can't layer the sale with other voucher codes.
