I'd go to another 1 too. Envelopes should only be 65 cents. If I wrap mine in the press and seal so they're real tight it's a regular stamp, but the price of that stuff is crazy. Saran wrap really mash out the air and when I took mine down to PO to check she said 45 but you're really safe at 65 cents. I know last boom I got alot of them on the 1st mailing with just a regular stamp on them. Who knows?? but she did tell me it came down to the clerks disgression. If I sent a manila out with just the basic F8 it's 85 cents I think. $1.10 is what it cost me for Canada
