ED - If you ordered and DID receive an order confirmation email, then your order has been noted at the store and should proceed just fine.
It seems that there are some issues over at paypal, and this seems to be affecting many stores, we are investigating the impact on our store. In light of this, please note that if you placed an order at the store and DID NOT receive an order confirmation email, then there may be a problem with your order, the best thing to do is to contact us! email us at: email@example.com
It should be said that most orders seem to be going through ok, but I have been alerted to two folks who experienced an issue.
Please note: We can only send store order confirmation emails to orders that are actually registered on the store, so if we're handling your order via email, then you will not receive a store generated order confirmation email.
