I wouldn't refer to it as 'stamps' so much as how much does it cost? To ascertain this amount simply go to the usps.com website then look under international where there's usually a table of sorts telling you how much the amount is in postage to mail whatever the weight of your item is. And just so you know, because people thing for some reason they need 'special' stamps or international stamps (do they have them specifically?) you CAN use regular plain old stamps that you use to mail letters from your house to the one next door or in the next state or states!! So once you know how much it will cost you then all you need to do is put stamps on the envelope & put it in your outbox. Provided, of course, you have stamps on hand!
1.
44 cents
One stamp.
Couple of 98c stamps, can be more is heavy
i dont know you tell me
one $0.45 stamp for a letter. more for heavier pacakages.
One. A standard .44¢ postage stamp.
If you are sending a normal-sized letter, you would need $0.49 total of stamps to mail it from Indiana to California. You could use a Forever stamp or a combination of other stamps that equals $0.49.
The same as all domestic mail (44 cents for the first ounce as of May 2009)
One. It needs to be a first class stamp and the letter needs to be one ounce or less.
It depends on the weight of the letter, not where it's going.. The rule I use it, Less than 5 pages one stamp. If the letter is 5 pages or more be safe and use 2 stamps.
about $1.56 for 5onces. go here to see all the options http://postcalc.usps.gov/
