As of June 10, one ounce of first class mail is 44¢. Every additional ounce is 20¢. So, a six ounce envelope would cost $1.44 to mail, or four forever stamps.
how many stamps for a 3.4oz envelope
If you envelope weighs less than one ounce, it will take one forever stamp or one current first class stamp. If the letter and envelope weigh more than one ounce, the number of stamps will depend on the weight and the denomination of the stamps.

I successfully mail CDs all the time with 2 stamps.
There are other factors to take into consideration when determining the cost of mailing, such as, dimensions of the envelope. The best place to check is the US Postal Service website to be sure to get the correct number of stamps for your envelope.
A 4-ounce large envelope currently costs $1.57.
If it weighs up to one ounce and is rigid and not extra thick you can mail it for 88 cents ( two first-class stamps). If it weighs 2 ounces the cost is $1.08. If it heavier or thicker, it will cost more.
It depends on how heavy the contents are and how big the envelope is.
