These are great File Folders and being store brand good price on them! Our boss prefers these for everything so they don't tear. Personally I think the extra weight is pointless for files that just sit in the file cabinets all the time but those that are out and handled a lot--they are great!
I use one folder each day for daily invoices and keep them in a storage box that holds 2 months worth of invoices. I used to order the cheapest folders I could but then I had to put cardboard in between them or they would curl up and slide into the storage box. These heavyweight file folders are strong enough that I don't have to support them. Cost a little more so I just watch for sales.
I purchased two boxes of paper that were supposed to come with a rebate. I have never filed the paperwork because it's too time consuming and I can't tell if I'm going to get a rebate on both boxes but I suspect only one even though the information makes it seem like I will get both. Too ambiguous.
