I buy lots of pet food and save the empty bags (making sure there are no lingering pieces of kibble, then folding and storing in a kitchen cabinet). When there is an accident, I sweep up the broken glass and pour it directly from the dustpan into a pet-food bag, roll it shut and secure it with a bit of tape. Because of the wide mouth, it all pours in, and the multithickness of the bag prevents cuts.
When sending in a check, money order or any type of payment with an order, do not use staples, tape or glue. This oftentimes destroys the payment, plus the order, as we attempt to take it apart. I don’t know if this has been given any thought by readers sending in mail orders, but it is very important.
