This link new Useful Stuff page now links to a number of products people mention at bedbugger.com. There are links to purchasing mattress covers, ziploc XL bags, food grade DE, and so on. This was recommended by a reader, and I hope it helps you.
The Amazon.com links there direct you to the types of products and provide a photo which you might find useful if you’re looking in stores. Plus, any purchases you make, Amazon will give Bedbugger a small commission, which helps keep the site going. Even if you’re buying a blender or a book, you can help Bedbugger (at no additional cost to you) by sarting from one of those Amazon.com links on the Useful Stuff page.
