Welcome to Flyertalk.

In most cases, Tumi will cost the same no matter where you go. There's not much discounting going on.

There is currently an end of season sale going on so you may get lucky, check the website to see if what you are looking for is included, so you know what you can get it for online before you go in. The sale does include some Alpha stuff.

There's also a Tumi Outlet store in the Seattle Premium Outlets, it's hit or miss what they have and how stuff is priced, but sometimes you can get incredible deals, sometimes not so good. Check if they will offer a warranty or not if you shop at the outlets, some of their stuff does not come with the warranty, some does.
