    --- TIC-TECH message:
    I made a purchase from Graybar this year. I called up and ordered some CAT5
    wires. I picked them up at will-call at their Seattle store. I wrote a personal
    check and still got the Seattle Schools price. I don't know if this is the
    exception or a common practice. I also ordered a hub, they were out of stock, and
    I got it within 5 days, delivered to my school, charged on my credit card.

    Good luck,
