Burberry for men ($30 or less online/in store)
Lancome Hypnose (I believe it can be had for about $30 online)
Gucci Pour Homme 2 ($40)
I love the other 16 or so fragrances that I own, but I think I could live with owning just these 3. I would absolutely love it if I could squeeze in Gucci Envy and Burberry The Beat somewhere in there. I guess that would be another combination-those two instead the 3 listed.
