Postage varies depending on weight and location, as well as the type you want. To the EU untracked mail should be 1.50€ and tracked mail is 4.50€. For outside the EU it's 2.20€ and 5.70€ respectively, plus 3€ if it's to be declared to customs (technically a bit risky if it isn't but I haven't had any problems so far either way).
I'd prefer paypal as a payment method but I'm receptive to any alternatives you may have!
