They are actually located in Richardson(right in the telecom corridor). Made a visit today and is impressed the way they are setup.

If you are on a business trip to Dallas, you have added advantage of buying tech books sans shipping costs(if your billing is out of state you don't need to pay any sales tax).

Their pricing is inline with some other entities like book pool.
