Usually Apple Stores in large City Centers have a larger array of Macs in stock. The Apple Store in Downtown SF has the Anti-Glare option available for 17" MBPs, though stock is limited.
If your Apple Store is in a small town and you have to make the trek, go a few miles farther to the largest City in your area for the machine of your dreams or cross state lines if certain areas have lower Sales tax than your local area.
I could've flown to Alaska and back and bought a Mac for less than the Sales Tax i dropped in store.
Amazon wasn't an option at the time, of course.
