Questions shoppers ask about Isotonix
What is the Isotonix shipping and delivery policy?
If you order eligible Isotonix products totalling $125 or more after discounts, you qualify for free shipping within eligible U.S. locations. Orders below $125 qualify for $6 flat-rate shipping. You may also select UPS Mail Innovations for $3 or UPS SurePost for $4 or 3% of your order, whichever is higher, when your order meets eligibility requirements.
What is the Isotonix return policy?
You can return most items within 30 calendar days of the ship date for a full refund, minus shipping. Contact the refunds team first for a Return Authorization Number. Your item needs to stay unopened, unused, and in its original packaging. Custom products and gift cards aren't eligible for return.
Who covers the cost of return shipping?
Return shipping costs and insurance fall on you as the buyer, not Isotonix. Since lost or damaged return packages aren't the company's responsibility, insuring your package for its full value protects you financially. Once your returned item passes inspection, your refund routes back through your original payment method, with gift card balances refunded first.
What payment options does Isotonix accept?
When you place an Isotonix order, you may pay with a valid credit card or debit card. You are responsible for applicable taxes, shipping, and handling charges, all of which appear on your order invoice. Your selected payment method must remain valid, and you must authorize payment before your purchase is processed.
