There are a lot of items that can be purchased very inexpensively at garage sales or thrift stores and sold for higher prices elsewhere. A few years ago I discovered that I could purchase good hardcover books at my local thrift shop for $1 or less. I realized that some of them could be sold on for $15-$20, which turns out to be a pretty decent profit.
Entrepreneurs play a key role in any economy. These are the people who have the skills and initiative necessary to anticipate current and future needs and bring good new ideas to market. Entrepreneurs who prove to be successful in taking on the risks of a startup are rewarded with profits, fame and continued growth opportunities. Those who fail, suffer losses and become less prevalent in the markets.

Communication is pivotal in the role of entrepreneurship because it enables leaders to convince potential investors, partners and employees about the feasibility of a venture.[97] Entrepreneurs need to communicate effectively to shareholders.[98] Nonverbal elements in speech such as the tone of voice, the look in the sender's eyes, body language, hand gestures and state of emotions are also important communication tools. The Communication Accommodation Theory posits that throughout communication people will attempt to accommodate or adjust their method of speaking to others.[99] Face Negotiation Theory describes how people from different cultures manage conflict negotiation in order to maintain "face".[100] Hugh Rank's "intensify and downplay" communications model can be used by entrepreneurs who are developing a new product or service. Rank argues that entrepreneurs need to be able to intensify the advantages of their new product or service and downplay the disadvantages in order to persuade others to support their venture.[101]
Leadership in entrepreneurship can be defined as "process of social influence in which one person can enlist the aid and support of others in the accomplishment of a common task"[122] in "one who undertakes innovations, finance and business acumen in an effort to transform innovations into economic goods".[8] This refers to not only the act of entrepreneurship as managing or starting a business, but how one manages to do so by these social processes, or leadership skills. Entrepreneurship in itself can be defined as "the process by which individuals, teams, or organizations identify and pursue entrepreneurial opportunities without being immediately constrained by the resources they currently control".[123] An entrepreneur typically has a mindset that seeks out potential opportunities during uncertain times.[123] An entrepreneur must have leadership skills or qualities to see potential opportunities and act upon them. At the core, an entrepreneur is a decision maker. Such decisions often affect an organization as a whole, which is representative of their leadership amongst the organization.

When one of your customers makes a purchase, you purchase the product from a third-party company (the drop shipper, usually a manufacturer or wholesaler) for a lower price. This process is as simple as forwarding the order from your customer, a process that can actually be completely automated. (Remember you don't have any risk here of buying inventory because the sale has already been made).
