Sitco, Inc. is a manufacturer of kitchen stools, and has been trying to do business with Walmart. After listening to several sales pitches, Walmart sent Sitco a letter requesting samples and indicated it would likely purchase if the samples were satisfactory. After it inspected the samples, Walmart sent Sitco another letter saying, $"$We offer to purchase $10,000$ of your No$.2$ stools that conform to the sample provided at your quoted price for said stools. Delivery two months from today. Your acceptance must be received in five days." Walmart intends to create what kind of contract with Sitco?
