Was going to buy from Toys R Us and thought I'd do a pricematch at Big W to save the hassle of driving to a Toys R Us. I asked the guy at the checkout to pricematch to $115.50, then he told me it was $90 already. MASSIVE saving for lego.
Comparison to other stores:
Toys R Us with 23% discount $115.50
Kmart $125 - Clearance too?
Lego site $150
May be in-store only. Possibly clearance? Purchased Mirrabooka WA.
When I tried Big W online it initially seemed that it had stock but now says "not available".
