Isn't it obvious.Yes.
Two 37 cent stamps (assuming that the letter doesn't weigh more than an ounce). But as you only need to put one 41-cent stamp on the letter, you could go buy some 2-cent stamps and save yourself some money.
42 cents. But if you don't want to buy a 42 cent stamp then go ahead and put 42 1 cent stamps on there.
Three 44- cent or forever stamps will work, but the postage is only 98 cents- you would wasting 34 cents. You can buy 98-cents stamps or 10-cent stamps at the PO.
a regular 44 cent stamp is all u need!
Yes
A (1) ounce letter is $0.44 cents. (2) ounce letter $0.61 cents. (3) ounce letter $0.78 cents. (3.5) ounce letter $0.95 cents. I would personally put (2) $0.44 cent stamps just to make sure, or take it to the post office to weigh it.
If Charlie uses $1.29 in postage to send a package to his sister and only uses 16 cent stamps and 7 cent stamps, he will use 5 16 cent stamps and 7 7 cent stamps.
Sure, as long as it equals to the proper amount of postage in the end.
Yes, there are two cent stamps. They have been available almost since the first stamps were issued. For many decades the postage rate in the US was two cents. Today they are mostly used to add to other stamps to make up a new rate.
Yes. All small values 1,2,3,4 and 5 cents are readily available at the Post Office. I am not sure about random values like 11 or 24, but you can put multiple lower denomination stamps if needed.
