...we've received several orders today/yesterday (and PayPal payments). We have had three DSL/phone outages over the past few days, so perhaps that's why your email bounced-back (???).
Our Storefront ALWAYS & IMMEDIATELY sends a confirming email to the buyer when an order is placed/completed (at the same time it sends us one). If you receive the email with your order on it, then you can be assured we received it as well.
