If you ordered online, you should automatically get an email receipt. But sometimes these get caught in SPAM filters or get automatically placed in the junk folder of your email program. So, please check that first.
Also, you should know the receipt is sent to the same email that you used on the order form. So, if you typed the email incorrectly, then you wouldn't have received one.
If you didn't receive an email receipt from us, then please submit a ticket so we can assist you further.
