The bill amends the Unfair Sales Act by revising the definition of "cost to the retailer" in 15 O.S. 2021, Section 598.2. The amendment removes the requirement for a retail markup to cover a proportionate part of the cost of doing business, which was previously set at six percent of the retailer's cost. Instead, the definition now includes additional costs such as freight charges and all state and federal taxes, while eliminating the markup component.

The changes aim to clarify the calculation of costs for retailers and wholesalers, ensuring that the definitions focus solely on the actual costs incurred without the added markup. The bill is set to take effect on November 1, 2025.
