Clearance Sale Thoughts

Things are still running my Clearance Sale, and I'd love some thoughts from those of you who have done it before. This is my very first sale ever. What have you done to promote your sale and/or to make it appealing to buyers? Obviously the prices are slashed as much as they can be on everything to start with. What might sweeten the pot? I want to get some of this old stuff gone so I can start filling the shop up with more new stuff!

I am upholding my promise to list one new item every time somebody buys one of the clearance items all through the month of September!
