How do you know if you have won anything?
some winners have been posted in the actual post of the item
When Santa delivers your prize
The winners are posted after the OP. Sometimes within minutes or it may be a few hours. All of the prizes from InterNACHI and Inspector Outlet will be mailed to you. No further steps are needed.
However, if you attempted to win prizes donated by vendors (HomeGauge, ADT-Secure24, Homebinder, BuildFax, etc.) you’ll want to check those threads to see if you were named a winner. If you were named a winner, then instructions to contact the vendor were given.
