Whenever someone comes from an ad, they'll swap out the number with a tracking number, then pass the call information back to AdWords.Hope that helps!

That way you are not constantly spending money just a little time to swap them out.  

We have also swapped out garage doors a few times for french doors and created additional family room space for a couple of clients.

I think finding equal collateral partners for the loan swap would be tough.

They maybe have a college degree (or not), they like to show up at 8 AM (or 8:05, or 8:10), grab a cup of coffee, swap stories at the water cooler, take an hour lunch (or 1 hour & 15 minutes) while they read a novel or play video games or stream the latest episode of GOT, and clock out at 5 PM (or 4:55), go home and that's their career.

Maybe swapping a tank water heater for on-demand, or maybe a good time to split services.
