darn it - got a flat

Where should I take the wheel? Do I have to take it to an Audi garage? Is it covered by warranty or scheduled maintenance? If not, how much should I expect to pay for a flat tire?
And I can't even leave work early to get this taken care of - first time in weeks that I've had a really busy day
PS. Try not to use the mini jack in the trunk. Use a floor jack if possible and don't forget to remove the lug nut plastic caps. There is a plastic (mini salad tong looking)tool in the spare tire area.
Insist on stick on weights if the wheel needs rebalancing.
