Hmmm, I usually see a 2:1 ratio for blood slaves, particularly if the one asking is the one getting blood slaves. Sure, they're relatively cheap for a blood nation, but they're not cheap at all for a non blood nation - which is generally who wants to buy blood slaves. Likewise, forging stuff "at cost" is usually only something you can expect from a good ally. Depends a lot on the situation I guess.
