I spent a couple hudnred bucks early last month sending change of address notices to all my vendors and clients.
Amazingly about 95% of my clients are already sending payments to the right address.
I can't say the same for vendors. I have had to verbally tell every single vendor I havce ordered from both this month and last to change our address. What really pisses me off is when they tell me I need to mail a written notice to them. I ALREADY DID YOU FLIPPING MORONS.
The moral of the story. Alarm users are 95% smarter than alarm distributors.
