We should be thankful for web technology that can compress time to add revenue for our account. Before web era we have to promote door to door or having very great real 

networking so we can promote our products. Plus we should have marketing skill for marketing our products directly to consumer that costs more time, budget, effort, and products often not sold successfully to consumer. So distributor or seller need to open a store, a strategic location store to maximize omzet and revenue, but still it will require more budgeting so being a businessman at that time will require a lot of expenses but uncertain amount of income. Now in IT era, with the spread of internet technology on every palm of people through gadgets, every person can open the faucet of income through web promotion, less effort, time, and money, but have positive certainty for selling products.
It is just the matter of moving products from supplier to consumer but it can produce extra margin that can become our income. Now we can get everything at everytime without spending more expenses for transportation and etc, just at tips of our fingertips we can supply consumer's demands or asking our demands to supplier, selling and buying directly, through the ease of technology.
