Isotonix FAQs
Does Isotonix offer a discount for first-time customers?
Yes. First-time customers can receive 20% off their first order of Market America-branded products, up to a maximum discount of $20. The code is displayed in the site header. Apply it at checkout to the highest-value item in your cart for the best result.
How does the Isotonix Subscribe & Save program work?
Subscribe & Save gives you 10% off every recurring order on eligible products. You choose a delivery frequency — 30, 45, or 90 days, or a custom interval — and the discount applies automatically each time. Subscriptions can be paused, skipped, or canceled at any time with no penalty.
What is the free shipping threshold at Isotonix?
Orders of $125 or more in eligible Market America products qualify for free shipping — no code required. Orders below that threshold ship for a flat rate of $6, with lower-cost UPS options available for lighter or smaller orders at checkout.
What is the MA Cashback program and how do I earn?
MA Preferred Customers automatically earn 2% cashback on qualifying Market America-branded purchases. Cashback posts immediately after each eligible order. Once your balance reaches $10, you can redeem it against future purchases on the site. You must be logged in as a Preferred Customer for cashback to apply.
Can I stack the Subscribe & Save discount with the MA Cashback program?
Yes. Preferred Customers who subscribe to eligible products earn 2% cashback on the already-discounted subscription price. Combined, the effective saving versus a standard one-time purchase is approximately 12%. Cashback is calculated on the net amount paid after the subscription discount is applied.
Does Isotonix offer buy-now-pay-later?
Yes. Sezzle is available on eligible Isotonix products, splitting your total into 4 equal interest-free payments. For example, the Daily Essentials Kit at $193.60 becomes 4 payments of $48.40. Sezzle availability is shown on individual product pages before you add to cart.
