Last week I waltzed into a shipping store with a few DVDs to send to my parents.  I had no idea how I was going to get them there, so I trusted their expertise.  This is the first time I heard about bubble envelopes.  The clerk put the DVDs in the mailers for me, and something amazing happened.  She somehow dropped them and stepped on them all in one motion, and trust me, she was not the lightest person I've ever seen.  When she picked them up, the DVDs were unscathed.  Those bubble envelopes are real tough, so there is no doubt that I will use them in the future.
