LizTD, there are plug-in apps that help you track prices on Amazon, so you can see how today's price stacks up. There's one called Traktor, another called Keepa... which you pick depends on your OS, but they're pretty helpful, as Amazon prices sometimes fluctuate a lot.

Btw, that set you link to is now $58 :-)

My sister bought me one like the one shown in the link Odin supplied. She uses it as a swimsuit coverup, a towel, and a scarf. It doesn't take up any more space than a shirt.
