Once you've computed your final total, send the paypal payment to the Lab. In the comments box, tell them "Order details will follow by e-mail."
Then send an e-mail to firstname.lastname@example.org. You can give it a title like "Order Details for Sally Brown" or whatever name is on the paypal account. Be sure to include the e-mail address the PayPal payment came from, the name of the PayPal account owner, the total amount of the payment, the date, and the unique transaction ID number that Paypal assigns to the transaction. Then list the items in your order.
Within a day or two, you should receive an e-mail from the Lab letting you know that they've matched up your PayPal payment with your order details. Works for me every time!
