I realized recently that I have never shipped a graded card, so what is the proper way given stories about cracked slabs. I was planning on using a bubble mailer, but should I use an extra layer of bubble wrap or cardboard perhaps?

A slab sandwhiched between two pieces of coragated cardboard in a bubble envelope works fine and keeps the weight to 3-4 ounces.

If it is worth any kind of of money send priority mail in a USPS Priority mail box. That way you won't have any problems.

I have occasionally used cardboard with graded slabs, but most of the time I just ship with regular bubble mailer and is fine. Never had an issue with just a bubble mailer. Short of a truck tire running it over, i think you will be good. Also, 3-4 ounces is right.
