Thanks for the tip!
But mate, how the heck is one supposed to know an industrial building over at Quarry Bay has a toy shop?
By the way, I forgot to mention that the Toys 'R' Us in Olympic City's shopping centre (near the MTR station Olympic, surprise surprise) were selling MP Grimlock for $800HKD a couple of weeks back.
Pretty sure it was a promo price, so not sure if it's still available.
