What are the categories of contracts in the following scenario?
An avid skier, Dr. Pearson decides to purchase a new pair of skis. He goes to a local ski shop and is assisted by the shop's owner as he looks at several pairs. He really likes a pair that costs $1,085, the most expensive set in the store, and says he will buy them if the owner will include bindings. The owner agrees and prints an order form with instructions to the shop staff for fitting the skis with bindings. Dr. Pearson pays for the skis and collects his receipt. The shop staff prepares the skis, and Dr. Pearson returns the following week to pick them up, ready to hit the slopes.
