Bit of a Niche "bargain" here so not expecting many votes however as fishing was a big thing for me growing up as a child I feel the need to pass this on. Further more may not be considered a bargain anyway.
Basically take your child/younger sibling and register for Swan Fish 2013 (Fishing Comp on the Swan River in Perth) Juniors cost $10 and receive a Jarvis Walker Fishing Rod and Reel set. For this you need to register for Swanfish at any Getaway Outdoors Stores.
