I have about 700 and am accumulating more. I smoke one per day, albeit a somewhat larger one which would mean two coronas. This is what you need to justify things to the wify:
1. The number you have on hand does not relate to how many you smoke per day, although it may increase the number that are given away. Don't mention the last part.
2. The internet will someday come under taxation and there will, probably, be special controls put on tobacco products because the states are trying to pass off high taxes as being good for you while at the same time profitting from your bad habits.
What this means is that by buying a lot now you are actually saving money in the future.
3. Keeping the humidor full stabilizes the humidity and protects the cigars.
This is all very logical and should convince anyone why it's important to have more on hand than are really needed.
4. This advice does not actually work in the real world with a real wife.
