If you're in need of cologne samples, just head to the mall and get them to give you some. My mom knows a lady that works at one of those places, and once every year or so when I walk by there with her, she'll literally give me a bag of the little sample viles. I mean... ONE of those lasts me for months--years, even! The last time I was there I got a couple dozen viles.

I've never tried to get any shaving creams or anything, though, so yeah, try web sites.
