are you folks really that skiddish?!?!
so what if someone rats you out? The only way they can prove it is by a controlled bust. And since they can't charge any of your customers for posession and get them to roll you under the bus, they dont have any real leg to stand on to set up the bust.
Try this, instead of useing currency, use silver or gold bullion. problem solved. Trade for honey to use. Trade for groceries. Trade for someones homegrown. GAIN, if you skiddish of money, trade for some things on your grocery list every week that is worth the same as what you would sell a bottle for.
example "hey man, can i pick up a few bottles of cider"
reply "yeah and on the way over pick up a 5 pack of Top Raman, 1 lb of ground chuck, and a loaf of wheat bread, and a carton of eggs."
or "yeah, can you stop by borders and pick up (insert title/author here)________
or "Yeah, 1 ounce of silver for a couple bottles"
or "yeah, I'm low on 9mm rounds, can you pick up a box of (insert favoirt ammo here)_____
or "yeah, BUT YOU BETTER CRACK OPEN THAT HUMIDOR AND BRING ME A "DON LINO!!!"
you'l have plenty of good barter claimed items in no time
it's fun too, because your friends stop by all the other time
