I have a book that weighs just under 4 ounces. I am using a 6 x 9 envelope for mailing. Can I mail this by first class parcel and still use the PBS delivery confirmation?  Postage on 4 ounces is cheaper than Media Mail for 1 pound. ($1.64 ), But I am not sure if I can use the DC, If not, I would not bother to buy the PBS DC for this book. I need a quick answer before I print my label.

I keep hearing there's a lower weight limit (what weight, I don't know) and a thickness limit (which is 3/4") to DC -- less than that, the PO doesn't let you use it, on first class parcels.

You can use the PBS DC.  Just make sure you cross out "USPS Media Mail' 

Thanks, Wendy, That  is exactly what I needed to know.

I use it all the time. The only problem I have encountered was when a book was very thin and pretty small and it was just considered a letter instead of a parcel. She let me send it with DC anyway that one time but told me I would not be allowed to do that again. So now if I get something that is small and thin like that, I throw in an extra book or a sheaf of paper or something.

I was just going to say, stick a piece of cardboard in the package as well. That would bring it up to 3/4 inch!
