I put up fuelcost.org during the recent fuel crisis, then got too busy to follow through with it.
It's only getting a few unique visits per month at the moment, so it's current value is purely based on potential, and with another fuel crisis on the horizon (Spring '06 according to experts), it has some potential for profit.
It's a Mambo 4.2.3 site with Simpleboard installed. If sale terms are reached, I'll transfer all files, database tables, and I'll unlock.
I don't know what it's worth, so I'll start by asking for $20.
