Abstract: Methods and systems for managing retail inventory are described, including automatically grading and pricing used or specialty goods (e.g., used clothing) based on market-based criteria. In one example, an employee at a thrift store can receive a shipment of donated used clothes. The employee can sort through each clothing item and enter information for each item, such as brand, type of item, condition, style and other desired information. Based on the information inputted by the employee, the system can accesses a database that stores information about similar items and corresponding market-based parameters, and automatically assign a price or other grading value for the clothing item currently being graded based on a predetermined pricing/grading algorithm. In this manner, a grading or price can be automatically calculated based on statistical market-based criteria. Advantageously, a relatively untrained employee need not have to speculate or guess a price for the used clothing item.
