I will need a couple of spawners for the new animal area that i gone get in flintwood, also if you got any eggs i would love to buy them as well, they may come in handy

Price Ill Pay:

Spawners: 7k - 10k depends on the amount of stuff I may have bought from you earlier

Spawn Eggs:

Cow: 4k
Pig: 1k
Wolf/Dog: 5k
Ocelot/Cat: 5k
Mooshroom: 4k
Sheep: 6k
Chicken: 1k

I wont change the prices if not the seller gives me a good reason for it - ! -

Just some friendly advice: Them prices are shocking. People will be being very foolish if they sell to you with them prices described.

What is the prices bad or good ?

http://www.noobscraft.com/guides/spawning-egg-prices/ - Just a guide for your prices.
And the estimated price for spawners in-game is 12500 Noobz, I believe.

I kinda set the prices after my own needs :p
