I need help in deciding which to get. I will have enough money to get the spy in cognac next Friday. But this crush that I have on the Balenciaga bag is getting hotter by the day. Should I just get the spy and just save up for the B-Bag later or should I get two B-bags (small and city)? HELPPP!!! Is the spy a better purchase? Is it comfortable ont the shoulder? I actually went into the B-Store tonight and the B-Bag is practically weightless.
