I agree - my understanding from someone who apparently was familiar with their previous shut down was that people were fudging sizes, weights, and the contents of the boxes. They used Fed Ex and apparently the relationship soured because of those things. The proprietary box limits the dimension issues to some degree, and they probably are more closely patrolling weight. More options are better, but that proprietary box thing makes it less convenient. I have boxes sitting around I'd use if I could instead of having to buy new ones.
