Suffocation Warning Bags - recommendations

Bookseller here.

In the last couple of years I started sending my fba inventory in suffocation warning bags in an attempt to keep them from getting quite so worn and torn in the warehouse. Things have improved, and I use them now for my fbm books as well. However, I still get some books back from the warehouse with the bag split open. I have been buying the least expensive bags and I figure I'm getting what I pay for.

Does anyone have any recommendations on good quality bags for as low a price as possible. I don't need big quantities - a few hundred at a time will do.

Thanks.
