You missed the really good coupon that just expired on 9/11 ($45 off $150). However there is this new one:
HALLOWEENFUN (exp. 9/30)
It is good for $10 off a total purchase of $50 or more. Use for any purchase below $100; otherwise use DISNEYTREAT, as the 10% will be more than $10 at any amount higher than $100 total. But if you keep close to $50, it's worth 20% off.
Unfortunately, Olszewski pieces are all pretty much over $100! Sorry.
The 10% is the best coupon right now. BUT, if you don't have a Disney VISA card you can apply for one AND if you are approved AND use it to make a purchase through DisneyDirect you will get $25.00 off your order. I already have the card so I'm not sure if you can use the 10% coupon code and the $25.00 off on the same order.
You can think I'm wrong, but that's no reason to quit thinking.
