One real tote, every spot sold to a sponsor, their giveaway bags bundled into the price. Move the sliders and watch who gets paid. Print pricing assumes a San Francisco digital-print shop, not overseas.
Assumptions: Stripe 2.9% + 30¢ per charge. Print run rounds up to the vendor minimum of 50. At 20 spots on the mini tote each sponsor gets a 3 × 2.9 in front or back panel, or a side wrap. The factory line is revenue to the print shop, their margin is inside it. Figures are per bag design, run it monthly and multiply.
