How many stamps do I need for this package?

Question

I'm mailing a large envelope but since its not flat its a small parcel. I used 7 49 cent stamps . the package contains a iPhone and its charger so it should weigh 9 oz at the most. I live in Ohio and the package is to go to new York so not very far. So is 7 stamps enough?

Answer 1

best to go to pdst office, that way you have enough, and not waste money for postage you dont need
