I think it just depends on your personal preference. Obviously, as others have pointed out, the hot tub is not offered very often. If you change your mind on Monday, then you might have to wait over six months to have another opportunity to purchase it. However, if you would be perfectly happy settling for a different bath tub, then don't waste the
KC. If a regular W-Shop tub is fine, you can use coupons to make it even cheaper and add to the accents in your room.
Personally, I don't have this item. I started playing after the last time it was offered (in December 2009 ), but I just don't have the
KC right now. If it's meant to be, then I'll find it again at some point down the road.
Anyways, good luck with your debate!
