I got a job as a hostess at a nightclub, and I've been working a lot - not much time to run around locating freebies, but here's some stuff for you.
I have a friend who signed onto SL, and I've been taking her around, getting her set up. Her's a place she found for me to pass on to you.
The Freebie Store is a HUGE place filled with items for free or $1, with nothing over $5. Again, you can find these free around SL, but if you want to save some time, start here. I have to say that the boxes are very neatly organized, and it's easy to find what you're looking for.
One warning - this sim is very populated, causing some straight flight problems. ;)
