One will never cover it. You need to know the size and weight of what's being sent back to you before you'll get an answer.

[quote="StevenQ"]You'll have to guess the weight of the envelope coming back to you. Assuming it's just a photo with maybe some cardboard, take the equivalent to weight it somewhere with a scale. Once you have the grams, convert it to ounces then go to USPS.com and calculate postage. Right now a first class stamp is 44cents. I predict you'll need 4-5. A forever stamp is same as first class stamp, but if the rate goes up it will always be good as a first class stamp. Those would be my choice as you never know how long it will take. Hope that helps.[/quote]


so i only need one stamp if its coming back to the uk?

sorry just really confused
