Sorry I haven't replied sooner, but preparations for Hurricane Bonnie have
delayed my reply.
AB Chance's website has a list of distributors on their webpage:

I was able to find a Dealer very close to home. The following is a repost of
information I provided to the reflector earlier this summer:
Some screw-type earth anchor information available from one of the largest
manufacturers, AB Chance Co. @ http://www.hubbell.com/abchance.
The Virginia distributor is JA Walder, P.O. Box 1272, Ashland, VA 23005.
Their website is http://www.walder.com, email is email@walder.com, and their
telephone is 1-800-335-3605.
The pullout strength of anchors is highly dependent on the properties of the
soil. Here are some pullout strengths for AB Chance screw-anchor models for
'NORMAL SOIL'. I don't know how to adjust the ratings exactly
for other types.....(* indicates galvanized). Soils with clay will provide
more pullout strength. Softer soils that have more sand and loam, or that
become saturated with water during season rainfall will have much less
holding power.
