Before you get too far into this post, I do NOT sell any land. "Clearance sale" simply means that the rental prices on these parcels makes them a good deal. The "buy" price on the parcels is the price of the first month of rent. I grew tired at looking at these great parcels go unused, so get them while you can. I may change my mind and put them back at the normal market rate.
Go to these sims and look for the orange colored parcels, after you have clicked on View, then Land Owners and Property Lines:
1- Luxury: http://slurl.com/secondlife/Luxury/3/124/23
2- Lavish: http://slurl.com/secondlife/Lavish/111/22/22
3- Serene:

4- Ecstasy: http://slurl.com/secondlife/Ecstasy/128/128/22
You won't be disappointed in the good deals you find, especially on the double prims parcels.
