Just wondered if others had the same experience...I ordered the KC leggings in two sizes, xs and s. The small fit best, so I kept that one, and figured I'd exchange the xs for the larger size so I would have two pairs (assuming I was going to get a lot of use out of them come fall and winter). I got charged full price when I went to exchange it -- I figured it would be an even exchange. Just curious if that was the norm?
