Where can I buy Asterisk related H\W not on the web

I’ll visit the US next week (Denver CO) and I’m looking for possible place to buy Digium cards or equivalent in some “real” shops and not onthe web, any ideas? suggestions?

Digium cards aren’t exactly off-the-shelf hardware. Unless you can find a VoIP supplier in Denver that will let you stop in to make a purchase, I doubt that you’ll be able to get the parts you want.

The only other thing that I can think of is that you might be able order some Next Day Air and have them shipped to your hotel.
