Did she really say she would be forced to buy the storage slip? You only buy a slip if you have more than one piece of armor for it. I didn't buy storage slip 03 until I had more than just Athos's Boots, if your dumb enough to buy every slip just because you can and have no armor to put on them and then whine and complain about the number of slips increasing, then you deserve less the less inventory space anyway.
