It's true, we've had people contacting us today with concerns about not receiving their shipping confirmation e-mail yet.
I can assure you that we're working our hardest to get all of our orders shipped out as quickly as we can, and people will be getting confirmation e-mails as soon as their orders leave our warehouse.
And I can also assure you that if you end up not receiving your order in the time frame you selected (if, for example, you paid for next-day shipping, and it takes an extra 3 days to get the order to you), then you can contact us, let us know what happened, and we can refund your shipping cost.
