I think this subject is now completely worn out.  It has been hashed,
rehashed and rehashed again -- and, as most have said at the end of
their posting, "add a little extra to be safe".

10 cents a foot, so if you buy 50 extra feet your cost is only $5.00.
How much do the smokers spend on a pack of cigarettes?  How much would
be spent on a fast food breakfast?  How much is two gallons of gas?

I think it's time to put this subject to sleep, and, as Jimmy Durante
would say, "Good night, Mrs. Kalabash, wherever you are!"
