I just bought two of ArtistsValley icons individually. Great icons and the ability to buy individual icons is amazing! I'm developing freeware and shareware so I can't afford to layout $100 at a time on icon collections. ArtistValley is one of the first places I'll be checking from now on for icons. Looks good and keep up the good work.
Your icons are some of the best out graphically and icons are one of those areas where quantity matters (because of the diverse needs of developers).
Heck, if you guys offered the ability to buy 5 and get one free I'd probably have bought 5 last night!
