Comfortable shoes....you will be on your feet, chairs are rare and usually occupied unless you're lucky and fast.
Take pictures and notes. Memories get blurred easily if you're seriously shopping. Bring a thumb drive of something You like; if they're serious, they ought to be able to play it, considering the technology of the day.
If you want to really give 'em a jolt....a small briefcase with an LP or 3. Listen for the gasp...;)
