A run charge is a decoration charge. The first color/location run charge is included in your unit price. For every additional color and/or location (side) that is imprinted, you will incur an additional color or additional location run charge. For example: if your logo is 2 colors you will have one additional color run charge for the second color in your logo.
A set-up charge is a decoration charge. For stress balls, it refers to the plate that is created to place your custom imprint or logo on the stress ball. A plate must be created for every color in your artwork. You incur a set-up charge for every color and/or location (side) imprint. For example: if your logo has 2 colors, you will incur 2 set-up charges.
