Great Design is the cheapest way of selling great goods.

Onur Cobanli explains:
There are many companies that make mediocre products work by creating great advertising campaigns for them (which also involves good design), for advertising and marketing is a very strong tool for good business, but an even greater tool is good design; because when you have good design, your customers, clients, and consumers contribute to your marketing and promotion; now your consumers and clients marketing on your behalf is very important because personal referrals carry much more trust and results in higher sales, and the endorsements is a very strong tool for marketing, advertising and in generally are great for business. Advertising and marketing, is also one of the highest cost items within a good business, so it makes all the sense to invest in your products as much as you could to make them market themselves; with good design you will either spend less in marketing costs or achieve more sales with the same marketing budget; it is profitable to invest in good design, it costs cheaper to market good design; good design sells easier.
