What alternatives are available to Cam for dealing with rising gas prices and reduced delivery charges?

Cam had always wanted to own his own business. He wanted the challenge of making the decisions that determined whether he would succeed or fail. He sorted through many ideas before settling on a delivery service for local retailers. Many of the local businesses were losing sales to online businesses. Customers liked the convenience of shopping from home and having products delivered to their doors by UPS or FedEx.
He developed a win-win idea for local businesses and their customers.
He would deliver any order of $25 or more to a local customer.
He would charge the retailer 10 percent less than the shipping cost that would be charged by the major parcel shipping companies. And he guaranteed same-day delivery for orders placed before noon, overnight delivery for afternoon orders during the week, and Monday morning delivery for any weekend order.
Cam’s business grew quickly as customers had positive experiences with his rapid delivery service. Businesses that had not used his service before began to call him for local delivery. Customers got to know Cam and his reliable service. He had never had a complaint of a late or damaged delivery. He added a part-time assistant so he did not have to work long hours every day and felt he would soon be able to add another delivery vehicle and a full-time employee.
