Let me explain my answer. If you can buy 13,000 credits with $20, then 6,500 credits is equal to $10. So, 3,250 cedits is equal to $5. So 1,625 credits is equal to $2.50. It usually costs that to ship even something this small because I have to pay for tracking to protect myself. I'm hoping to get more credits for this. That's also why I use the "time is money" option and place it on auction for so long--more people can see it and watch it or bid on it :)
