I am a Coke guy myself. My great-great-uncle invented it right after the Civil war. and no I did not inherit any of the company, he was a bad boy and the courts took it away from him.
Listia has a secret. If you bid on something and you do not have enough XNK they will charge you the going exchange rate and sell you XNK. I tried it once and it worked. right now 1 XNK = .0169¢
Listia does not just sell INK like they did points. This auction is for 1350 XNK. Suppose you have 500 or 1000 XNK. You click on BIN button and listia takes the 500 or 1000 from your account and then bill you for what ever is left. A listia support person told me this and I tried on an auction that I did not have enough XNK. Listia took a few dollars from my credit card on file. It was correct for the amount of XNK needed X .016¢
Sorry. My BIN price covers the cost of the bank + 10% for listia + my postage + about 15% profit. I can lower the XNK if you pay the shipping through paypal. How much XNK do you have?
