That argument fails for sets that contain a lot of very low-cost items, like resistors, that can not be reasonably sold in 1's and 2's. But the other arguments against selling sets (most notably the 'what to include' problem) are still very valid. I sell one beginners set ( http://www.voti.nl/shop/p/DUMMIES-SET-1.html ), and it sells reasonably well. The 'what to include' problem is a bit less severe here, because the book dictates what to include (but I left out the unreasonably expensive and/or too heavy items). And the book author has already defined and debugged the projects, so no need to include that in the price. In a few months I expect to start selling another set for a Dutch PIC/Jal book ( http://members.home.nl/b.vandam/boek/micro/micro.html , page is Dutch only). I must add that I sell such sets not only for the profit on the set itself, but also because I hope to attract new customers.
