I also agree with Brice. The package sizes are a bit frustrating. The bigger size packages are handy when your a professional of course. But looking back at the days when my father's body shop was still operating, we mostly used a couple of grits a lot, but others only on occasion. From both 120 and 240 we used about 3 or 4 100 packs a week, but grits like 40, 60, 400 or 1200 were only used very rarely. So buying large packages of the latter was not economical, but fortunately we had a very good supplier that would let us order such grits in any amount we wanted, starting with a single disc.
Right now I'm not in the professional paint business anymore, but because I do know how to work like a pro, people keep asking me if I can do jobs for them, working on their houses or cars. It's enough to be busy for a couple of hours every week, but since I got me 3 Festool sanders now, the RO150, the RTS400 and the DX93, it's not enough to warrant purchasing the 50 or 100 size packages for all 3 of them. Especially not when you consider all the different types of abrasives Festool got.
I got a supply of 4 different types of sandpaper now, Brilliant 2, Cristal, Saphir and as of shortly, Rubin. Because I want to work efficiently and get the best type of paper for the specific job. And the right grit of course. Say you want to have a minimum of the most used grits available, then I'm looking at 40, 80, 120, 180 and 320. That's 5. Now add this all up and I'm looking at a supply of 3 machines x 4 types x 5 grits = 60 different packages of sandpaper I have to have at hand. (Not to mention I want to add the ETS125 and DTS400 to my collection very soon. Another two different sizes.)
Oops.
Well, not oops. I'm very happy Festool delivers such an outstanding collection of sanders and sandpaper, but for me, it would be best suited if I could buy them in 10 piece packages. Because buying the bigger packages is not affordable for me. As a result, part of the Festool range is OFF LIMITS for me. I don't like that.
Now there are some 10 piece packages, but unfortunately only in the lower grits. Last week I needed Rubin or Brilliant 2 in 320 grit or higher for the RTS400, and it was just not possible. Some time ago I was working on a car and would have loved trying out Titan, but Titan is not even available in small packages. I went to a local body shop and got me some 3M paper. A missed chance for Festool because if Titan was available in 10 piece packages I would have used that.
So in short, I want more availability of Festool's sandpaper in small quantities.
