KAI scissors, love mine! $$ They always have a booth at Expo. Fabric ~ no, you can get that a LQS and usually not much in Expo 'specials'.
IMHO I would look for 'gadgets' that my LQS might not carry (that interest me/you) ~ rulers, Martinelli ergonomic rotor cutter. Or patterns that catch your eye, but have not seen before. Marti Mitchell, Eleanor Burns, Kay Woods all have booths, and a few more that I cannot remember, so if you interested in their rulers/books/patterns, buy now and no postage expense.
Now I have been known to spend more than $100 at Expo
