If you like color … if you like bulbs … all different kinds of bulbs... I can't recommend these guys enough. I ordered from them a couple of times when I lived in NY.
COLOR BLENDS <-- linky
Then sell bulbs in bulk … so they're pretty economical vs what you'd pay at the Home Depot or Lowes or wherever else... and they're of much better quality. They sell single colors or in some pretty spectacular color combinations. Even if you're in a part of the country that doesn't really get proper "winters" … such as California… they can provide you with insight on how to get bulbs to work in your area. Ohh... they offer a free catalog too!
