I started out at $140 + $20 international shipping because I wanted the collectors edition.
After the Wasteland 2 announcment I upped my pledge to $250 + $30 international shipping.
The last few days I was thinking about upping my pledge to the $500 tier, just to help out OE. On Friday I was informed, that i will get a little extra payment this month. After a lot more thinking and calculating I decided to back the project with $1000 + $30 internatonal shipping. I know, that I don't have to add the shipping costs, but I want that every last cent goes into the project.
