I found a pair of Big Star jeans at the Buckle that I love. They are called Casey K. I keep watching for them on Ebay or for the Buckle to go on sale or clearance. How many types of Casey K jeans do they make? There are a lot on Ebay but they are never the ones I want!? How often do they come out? When might I expect a sale or clearance on them at the Buckle? Thanks
