Big Snorlax Bean Bag 50% off at EB Games eBay. This is also available on the EB Games official store if eBay isn't your jam.
Don't think you can use extra discount codes on top of this.
From the promo email I got from EB Games, seems like it ends 24th of March or while stocks last. (If I remember correctly last time this was posted it sold out real quick)

EB Games link here
Edit: There is also the Boo variation for the same price here
Edit 2: Seems like eBay store has been ozBargained; main site still has stock but shipping is $11.45 instead of $5.95.
Edit 3: eBay store is back in stock again! @ 1:12pm
Last edit: Seems delivery is not an option anymore on their site; floor stock only left.
