The three key aspects that a company must consider when developing a successful loyalty and reward program complete satisfaction of the customer needs, give the customer ultimate pleasure in buying the services or products with their loyalty program; in addition, if the consumer spends more genuinely they get more back on their loyalty or reward program, which they will want to focus on the same loyalty program that offers them savings. Customers frown upon any changes to their loyalty program that is not totally benefiting the consumer. “Loyalty program managers are frequently asked to find ways to tighten down budgets within their programs; it is also the case that senior executives do not always have data demonstrating the importance of their program as it contributes to return on investment or ROI. Consequently, programs are often cut or changed in ways that may negatively influence consumers”. Many customers just love their reward program with their vendors; furthermore, it makes the customer spend more with the vendor as well. For instance, I truly love Steven Madden shoes, they have a rewards program that is amazingly great; moreover, you get points for just signing up for the rewards program. All companies are gearing for customers to have a death do us apart relationship with their services or products based on their loyalty program.
When developing any time of advertising strategy to lure consumers to buy their product or services; consequently, you will have a deal with cost or decrease in the value of the company in order to maintain the loyalty or reward program. For example, “Restaurant chain Chart House program, the Aloha Club, offered free around the world trips to any member who ate in all 65 Chart House restaurants. Unfortunately, the company underestimated the zeal of its 300,000 members. Forty-one members qualified, costing the company a considerable sum of money” (Winer, 2016 pg. 429). Many consumers think they are getting great deals; in addition, at low cost too. Customers and the companies tend to try to get over each other in this marketing structure. “Reward programs are incentives designed to create loyalty among customers with the idea that they can provide the best rewards to the “best” customers. Loyal customers are, by definition, less price-sensitive customers. However, managers frequently question the value of their reward programs and wonder what, if any, incrementality is gained from offering rewards for customer patronage. Consequently, managers are frequently challenged to think of ways to manage their loyalty programs that reward high patronage without creating “deal” seeking customers and without further discounting price”. Consumers only want the deals; consequently, the company wants the long-term shopper, without a return of investments

Martin-Pullin Bicycle Corp. (MPBC), located in Dallas, is a wholesale distributor of bicycles and bicycle parts. Formed in 1981 by cousins Ray Martin and Jim Pullin, the firm’s primary retail outlets are located within a 400 mile radius of the distribution center. These retail outlets receive the order from Martin-Pullin within two days after notifying the distribution center, provided that the stock is available. However, if an order is not fulfilled by the company, no backorder is placed. The retailers arrange to get their shipment from other distributors, and MPBC loses that amount of business.
The company distributes a wide variety of bicycles. The most popular model, and the major source of revenue to the company, is the AirWing. MPBC receives all the models from a single overseas manufacturer, and shipment takes as long as four weeks from the time an order is placed. With the cost of communication, paperwork, and customs clearance included, MPBC estimates that each time an order is placed, it incurs a cost of $65. The purchase price paid by MPBC, per bicycle, is roughly 60% of the suggested retail price for all the bike models available. The inventory carrying cost is 1% per month (12% per year) of the purchase price paid by MPBC. The retail price (paid by the customer) for the AirWing is $170 per bicycle.
MPBC is interested in making an inventory plan for 2011. The firm wants to maintain a 95% service level with its customers to minimize the impact of lost orders. The data collected for the past two years is summarized in the following table. A forecast for AirWing model sales in upcoming year 2011 has been developed and will be used to make an inventory plan for MPBC.

To the Internal Revenue Service, the reasonableness of total itemized deductions depends on the taxpayer’s adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger than average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on adjusted gross income and the average or reasonable amount of itemized deductions follow.
