I've seen this before and now i'm seeing this again on USPS website, whats these labels for or how does one print just a bar-code for a letter or package? Meaning how would i be able to print just a tracking number without paying for a whole label?
Or is this for a regular box which has to to and from address and all you need is the tracking? (meaning its for a regular priority mail parcel and instead of re-entering all the info you just print a tracking for it? or is there an easy way for .50 cents or whatever to get just a tracking?
