Celia, you can always use the Bay's free shipping as a way to confirm they fit and what size you need, then order one of the other colours from elsewhere... Daria's Amazon link maybe.
Lisa, I have no idea how store stock compares to online stock. Ironically I ended up near the Bay last night, but given I'd placed my order only hours before I didn't go in. Would have been too annoyed if I could have tried them on and walked out with them!! (or not)
