Spa on a budget (<$20)

Scary women from a spa company were walking around the psych department yesterday trying to sell a package spa deal. They were definitely pushy... but what can I say, they were also succesful. I am very much looking forward to my four visits for $13 each.

I'm sure that many of us would love to get full-body massages every time we were stressed but alas, that pesky little thing called money (and for some of us, singledom), tends to get in the way. The question for today is how else can you get a totally rejuvenating spa experience? (without being harassed by spa salesreps during a time-limited offer)

Do you know of any great products?

To get us started...
-Pier 1's biscotti-scented candles...a bit strong, but pretty heavenly
-Sunshine Spa has a Tangerine salt scrub with ginseng and dead sea salts that is wonderful as well (I found it at Wild Oats while looking for an alternative to spending an arm and a leg at Origins for their ginger scrub)
-and in Miami, of course there's always the possibility of hopping in the ocean...mwahaha
