Typically, you should receive an email containing your order number as soon as your order has been successfully paid for. If you haven't received an order confirmation email, please consider the following potential issues:

Verify Your Email Address: First, ensure that the email address you used to place the order is accurate and spelled correctly.

Check Your Spam Folder: Sometimes, order confirmation emails can end up in your spam or junk folder by mistake. Please take a moment to check these folders to see if the email has been misplaced.

Payment Confirmation: Double-check that your order payment was completed successfully. If the payment didn't go through, the order confirmation email may not have been triggered.
