I know you're like the eBay goddess around here! I need to start selling off MIL's crystal collection (it was sizeable and I'm only keeping about 1/3 or less) and a good amount of it is collectible Swarovski. I think I'll have a better luck/profit selling through eBay than just local CL. I've only ever bought off eBay before though, never sold. One thing I know is that I should give a postage calculation up front, but not sure how to go about calculating that easily or accurately. Any tips, tricks, and advice you can share?
