its like this, you get an order for you manufacturer, you want 10000 widgets by end of month, come endof month you get 10000 widgets.
now you put the same order in for next month, but the widges sell out in 2 weeks and don't last the whole month. so for 2 weeks your waiting for you next months 10000 widget order, but in the meantime your customers that come after customer 10000 is wanting a widget too, but with no stock on hand they cant sell. so by end of month when you get your original 10000 widget order most of them are sold already so now your left with 1000 widgets for a month that is selling at 10000 per month.
in the meantime you see your selling widgets much faster than anticipated
thus you call your manufacturer and order 20,000 widgets for next month AS WELL AS and additional 10,000 for this month.
now your manufacturer who was antipating on making you 10000 widgets for next months order, now has to fill a 30000 widget order for the following month instead of 10000 as you antipated. now its a time crunch, especially if you can only produce 12000 widgets a month at the current production rate.
bottom line, BE PAITIENT GRASSHOPPER! poop SELLS OUT SOMETIMES>
If i cant find a widget i want at one place, i ll look and see if i can find that widget somewhere else. if its only availabe at Widgets R US and they are out of stock, i buck up buttercup and wait like the next guy.
