1) Don’t fill your freezer with ice trays! Instead… (an hour before your sale begins) just grab a bag of ice at your local convenience store.
3) Hit your local restaurant supply store! Snow cones somehow taste even better when in the small paper cones and topped with a brightly covered straw. Flavored syrups (in all the variations) are available - just like your favorite coffee stand. I’ve seen variations at Target, but (in the NW) you can buy the real deal for a fraction of the cost at Cash&Carry.
