Anyone buy from Sun Hs Warehouse Group?

[Chris Martin]

They advertise (on CL) Hardie siding, 7" face, for $5 a board. Not a bad price. Looks like they sell Mi Windows at wholesale prices. The pictures look like they are the builder grade products... targeting the flipper and landlord. Not sure what sizes, but pricing starts at $40. Just curious if anyone has bought from them. Not sure if there are minimum orders or quantities.

They are physically located behind the Ray Price Harley Davidson off of S. Saunders St downtown. I have no affiliation, but am looking for siding & windows for an 18 unit apartment.
