According to USPS.com...
I can add USPS tracking for only 20 cents, if I print it online, or 90 cents, if I apply it at the post office.
So, why can't I simply print 1st class postage, via Auctiva, and handle the tracking the way I want to?
I don't have to ship by FC parcel to have "tracking, Letters do have tracking. I know they have to be at least 3/4" thick, so all I do is toss a styrophome peanut in the envelope, and it qualifies.
I mean, how else can I mail someone, something that's super light like a baseball card, or 4 tiny screws, for the cost of a 1 ounce stamp, via Auctiva?
