Question on Tyvek bands for selling bags

  1. I have a no return policy should I still be using those Tyvek bands and if so why? thanks!!
  2. You may still have people who try to return something to you without asking first, and they may do a bait and switch. If you put the tyvek band on it, they cannot remove it without doing damage and you'll know that they have switched bags on you. It cuts down on fraud.
