There are a lot of shoes marked down to $30-$90 (depending on your budget), and the "get the second pair for $10" counts for sale shoes as well!
As an example of what you can get from this sale, I walked in L&J yesterday and walked out with these first two pairs of shoes: http://www.carbonchic.com.au/2012/08/salacious-sales/
Both all-leather and $50 all up ($25 each, down from over $100 each).
Don't know when this sale will end—when the store closes down, I guess. There are still plenty of styles left and a lot of bigger sizes really really marked down (size 9/10). There are MENS shoes here as well as ladies!
