Okay. I see now. The large shoulder bag is actually a tote and retails for $348. It has a different strap placement than the medium convertible bag. Yes, it looks like Nordstrom has two sizes for the medium convertible bag. Even MK's website doesn't show a large convertible bag. Maybe it's a Nordstrom exclusive. And, of course, the pricing is all over the place on the convertible bags.I still don't know how to post links, but if you look at the dimensions of the large shoulder bag on Macy's vs. the large convertible on Nordstrom, I do actually think they are two different bags. I really don't understand why different stores call these bags different names (& sometimes colors for that matter). I completely agree that it does become confusing.
