This is the businessman:

Here are you respected real working idea "small" business, I have been using it for 4 years:
1st Purchases a loosened cognac drink in a tank of 5 liters for 700 rubles. (Fresh course of course)
2nd They invite friends to come together and say so to drink.
Three From each friend, the collection (stack for drinking) is 200 rubles, with an explanation that for 200 rubles in a strong alcohol store, 0.5 liters are not real to buy.

Let us call things by their names, 700 rubles. For 5 liters - this is not a cognac drink, it is an underground car, with a dye and flavor. You are personally lucky with the supplier, once you are still alive, and so at all - I do not recommend. The health consequences of such savings can be much more severe.
