Midland and apparently Kalamunda Toyworld have an in-store promotion that ends on the 16th. It's a sheet in store (one per customer) with a bunch of coupons that give either a 50 (only one of these), 30 25 or 20% discount. You choose which one.

Conditions include one coupon per item and the item must be full-priced. I used my sheet to get a RTS deluxe for $15 and another for $21.
