Return shipping

I am open prefer cash. But will do cash app or PayPal. I try to make it easier on those that send cars into one of my events. Only reason I prefer cash is it's easier for me to keep it separate from my living $. And I can keep track of it like a business and know how much I can spend on prizes and returns without coming out of my pocket. Or using the race $ to spend on house stuff. If that makes sense. But I am willing to do PayPal or cash app to help builders mail in to me.  I want them to have fun racing. Not stress over sending the cars off or worrying about getting them back. I personally always return. I only have one set of cars I can not get returned because of change of address. 

What about for international entries, where getting hold of US Dollars isn't as easy. Can we send equivalent of our own currency or is it better to get it changed?

I am no race host (maybe one day but just got my drag track up and now in the process of rebuilding already) but as a racer, I honestly prefer cash apps/PayPal. I rarely even carry cash on me now (maybe a couple bucks sporadically). It also makes it so that $ isn't lost somehow. I have already had a few scares with the USPS...

Just my 2 cents...
