Computability
A word to the wise! If you order by mail, DO NOT ORDER from Computability.
After much haggling, and being told that my order has shipped on four
different dates, I have yet to receive my order after 4 weeks. Every time I
call, I am assured that indeed my order went out yesterday. This may be a
rare instance in the history of Computability, but it only takes once to
lose customers.
