AN UPDATE!
I returned the white GST today! The SA there kept asking, "Are you sure? You know its price has increased since you bought it, right?" etc, etc. but I returned it! It was over the 14 day return period, but I was able to return it just fine. He didn't really even inspect the bag, either...just took a look at the price tag and that's it. I thought they were strict about returns, but I guess not!
So there you have it: I still have the m/l white Classic Flap w/gold hardware and the black Jumbo with gold. I also have the white Jumbo with gold coming in!
Thanks for your input, everyone!
