This Money Back Guarantee is seperate from our standard return policy which only covers unopened products. This is an introductory offer for a limited time only. The money back guarantee applies to the first bottle only. It's only common sense to buy one bottle first to prove that it works for you and then when satisfied with the product to make a multiple bottle purchase. To qualify you must return your receipt along with the remainder of the product left in the bottle. Make sure you bought it from us - "The Rainbow's End". We can not refund purchase price on same brand products bought from other distributors. Just call our toll free phone to request a return authorization number (no questions asked) and return the product and remaining capsules along with your receipt and a full refund less a small processing fee (shipping of course in not included as that is an accrued cost) will be applied to your credit card within 10 business days. In case of purchase by mail a refund check will be mailed to you.
