About vinyl banner 7'x12' pricing
Priced per unit with quantity breaks. Vendors quote steps at 1 / 5 / 10 / 25 / 50 / 100 / 250 / 500 / 1000 units, and the per-unit rate drops at each break.
Should I buy new hardware every show?
No. Commercial-grade hardware is reusable for years. Buy the frame once and reorder only the printed graphic, which is the cheaper part.
Why do retractable banner quotes vary so much?
Mechanism grade. An economy unit and a commercial one look alike on paper but the cheap one fails sooner. Pin the hardware grade before comparing.
