You can buy 16,000 credits for $5 and the shipping will cost me over $3 so you'd be paying around $2 for the hockey puck, new in package. If you can buy it for this price somewhere else I guess that would be fine.
I'm sorry that you're having such a rough time. I understand because I too am very poor with 5 kids, no husband, disabled, and trying to survive. Unfortunately as much as I'd love to help you I would at least need $3 to ship the package to you even if I gave the item to you freely. I would love to help you but at the moment I'm in a pretty bad position myself.
