 20.       Q.        Does Dunnage Systems sell a reusable bag?

A.        Yes, however, our concern in selling a reusable bag is as follows:

1.  We do not have any control over how a bag is used; therefore, we can not guarantee how many times it can be used.

2.  The bags have a significant upcharge. Most customers do not have enough control to get the bag back, thus they pay for a bag to reuse that they do not get to reuse. Many times bags are punctured to release the air and thrown away. However, we have added an additional label to try to eliminate this problem.
