If you ordered and didn't receive an order confirmation or receipt, first check your email's spam or junk folders. Sometimes, the messages will get caught up there. If you aren't finding the message in your junk or spam folders, then double-check additional email addresses that you manage as you may have used an alternate email account.
If not found, it is possible that there may have been an error or typo you made while inputting your email address during checkout. If you feel that to be the case, please contact our service department by submitting a ticket (customer-support.naturehills.com) or by calling our customer service department toll free at 402-934-8116.
