I bought some seconds from Sierra a couple of years ago and they were better than those.
I have the USPS web site saved and print my own flat rate labels at home.True that.
I just wish they'd sell "forever" postage stamps in the various flat rate box denominations so I could just slap one on and stick it in my mailbox whenever rather than have to drive to the P.O. on my dinner break.
I'd also appreciate a "mini" box for $4.65, about 2x2x4".
