Im actually a collector. Have about 30 bottles between my son (16) and I.
Its a whole thing, kind of like watches, sneakers, baseball cards or anything else collectible.
I've got some nice stuff, and find it worth it. I can pretty much guarantee no one can smell me outside of a 2-3 ft bubble. You pick certain ones for certain occassions (work, date night, etc). Keep the clean soapy non offensive stuff for work, stuff that appeals to the wife (always, but especially for date night). Gotta keep it fresh after being married for 23 years.
Anyone wants advice I can steer you in the right direction!
