brainMD's headline offer is 50% off new sleep formulas, but the brand actually has tiered deals that give increasingly better discounts as your basket grows. The right choice depends on what you're buying and how many items you add to your cart.
Buying a single item: If you're picking up just one product, take the 10% off when you buy 1 product deal. That's the automatic floor discount for any single purchase at brainMD.
Buying two items: Once you add a second product to your basket, you have options. If both items include the 15% off when you buy 2 products deal, use that for a stronger discount than the single-item tier. However, if you're specifically after Dr. Amen's Favorites products, the buy 2 or more and get 15% off deal will net the same result, so either applies.
Buying three or more items: The 20% off when you buy 3 products deal becomes your best bet for general purchases. This beats all the lower tier discounts and is brainMD's strongest blanket offer for larger baskets.
Shopping for specific categories: If your whole order is new sleep formulas, the 50% off new sleep formulas deal cannot be beaten and should always be your first choice regardless of basket size. Similarly, if you are stocking up on Peak Energy products, the 25% off Peak Energy plus Energy Collection deal is worth checking. For sexual wellness formulas, 10% off applies automatically.
First time or returning customers: If you haven't signed up to brainMD's newsletter yet, do so to get 10% off your next order. This is valuable if you are under the thresholds for the automatic tiered discounts, though note it applies to your next shop rather than your current one.
Only one offer applies at checkout, so compare your basket against the available options before you pay. Category-specific deals like the sleep formula or Peak Energy discounts typically beat the generic tiered discounts, but the 20% off at three items is hard to pass up if you're doing a broader shop.
