People waste way too much money on this crap (and this is why I own stock in P&G)
Unless you have skin issues, a wash cloth and cheapo bar soap will leave you smelling plenty good. I use this shampoo:
I think it smells good and my hair is healthy... and it cost somewhere around $1.50.
I will splurge on some decent cologne (Lacoste Red, Polo Black, Burbury Brit are my preferred choices) but a bottle will last you forever if you use one spray daily so it is a good investment.
Toothpaste, whatevers on sale. Mouthwash, the cheapo store brands. I'm a cheap bastard I guess.
