Just to answer a few common questions:
1. The invoice should pop-up a small yellow notification box after payment has been detected (this is usually within 1-2 seconds). Some browsers or <noscript> users aren't seeing that.
You can always refresh the invoice URL to see the updated status. If it says "Your Order has been paid in full" then you are done.
2. On the receipt it says "a copy of this invoice will be emailed to you."
This is actually true only for orders that utilize the Bit-Pay shopping cart (from sites like http://bitcoinmagazine.net
Since BFL uses a WordPress shopping cart, the confirmation email actually comes to you from BFL. After payment is received, you should get an email from BFL with your order number. BitPay will not send you an email. Just bookmark the URL of the invoice and that's all you need.
If you guys have any further questions, just ask.
Thanks again for your orders.
By the way, if there was any doubt about bitcoin's usefulness for cross-border commerce, we all shattered that over the weekend. The Wall Street Journal online has picked it up. This is a nice boost for bitcoin!http://www.marketwatch.com/story/bitpay-shatters-record-for-bitcoin-payment-processing-2012-06-26
