heheh funny thread..
The CAC Idea was a good one..
It rather depends firstly on what you can do yourself.. If you’re an SEO expert for instance .. you wont be spending money there 
I do most everything for my sites the ‘free way’ but I could find lots of ways to spend some cash, if I had it ..
I search the internet for places that allow me to add links, folks buy links from me, and thats definately an idea for spending cash… If ya find a nice PR6-7 site, I betchya you can spend it all up in one shot lol.
If you don’t write your own content, thats a consideration, lots of nice words for search engines to eat up.
There are programers, and coders (and maybe those are the same thing, it beats me ) you can hire here. SEO experts.. etc.
You can buy new graphics, providing you’re not a graphics guy, they dont do much as far as improving ranking, but they sure are pretty! hehe
If you have a forum, you can hire folks to post in it..
I myself have never had any trouble spending cash, but those are some popular options here at CAP .. Personally, I prefer a nail salon conveinently located to an espreso stand
