About custom paper tape, 2"×60yd pricing
Priced per unit with quantity breaks. Vendors quote steps at 1 / 5 / 10 / 25 / 50 / 100 / 250 / 500 / 1000 / 2500 units, and the per-unit rate drops at each break.
Why are quotes for the same power bank so different?
Vendors source from the same overseas catalogs but mark up the base unit, the decoration, and the freight separately. Ask for the catalog item number and quote the same decoration to compare fairly.
Is a setup charge for branding normal?
Yes, but it should be one time per logo and per method, not repeated per color or on a reorder of the same art.
