Sample conversation. You ask: "Which orders still need to ship today? Find the cheapest label for each, unless the customer asked for a carrier." The assistant uses Postsale to search orders and get rates, then answers: 6 orders are waiting, #4501 to #4506. Cheapest rate for each, and the carrier the customer asked for where they did: #4501 Sarah Chen, Springfield, IL: USPS Ground Advantage, $6.40. #4502 Dale Pruitt, Knoxville, TN: USPS Ground Advantage, $5.90. #4503 Rosa Delgado, El Paso, TX: USPS Ground Advantage, $8.17. #4504 Kevin Tran, Seattle, WA: UPS Ground, $28.84. #4505 Beth Ann Riley, Montpelier, VT: UPS Ground, $29.83. #4506 Tom Okafor, Toronto, ON: FedEx International Ground, $31.40. Total $110.54. Which ones should I buy?
