How many stamps for mail?

This might sound kind of pathetic, but I do not know how many stamps I should have on my envelope to mail it.

I want to send a donation to Sythe, which has to be done via mail.

I live in the New Jersey, US and I need to know what kind of stamps/how many to send it to New York, where Sythe lives. Thanks for the help guys. I mailed only like 1 time before, and my mom practically did everything for me

 

Firstly, The place where your mailing it too isn't to where Sythe lives, it's to A P.O Box which is owned by Matthew, the Sythe Administrator.

Secondly, You don't need to donate through the Mail, you can do it through PayPal with a member called "Spyike270." Click Here for the link explaining how to do so.

Thirdly, Use the US Postal Service website calculator to find the cost. [Link]
