Sometimes you need to poke and prod Savvy a little on issues that they don't deem immediately serious. When I was missing the hardcore kit in my bumper order, they had it figured out and shipped within two hours of my first email. If you email them about something that isn't something they've already messed up, it might take a follow up email.
When it comes to shipping, they have a process that refunds you anything over the amount they actually pay. Most of my orders have been partially funded on shipping.
And don't bother calling, email them instead. I've had Katie pick up the phone a couple times, but it is still just easier to email.
