If I remember correctly the £137.99 was initially Amazon price matching Smyths' price of £149.99 combined with the Smyths £12 off purchases of £100 or more promotion. I missed that but bought the Docks at the current price, and the City for £199.99. They don't exactly fit with my planned 'realistic' city (the modular buildings etc), but they're such fantastic sets I couldn't resist. I think once built I'll set them apart as a kind of densely built up island with a bit of custom work to extend them out a bit...
Got it for my son for Christmas its his first set since he started with the juniors stuff so going to build it together.. hoping he lieks it so we can get teh rest of the Ninjago stuff lol.. Good Luck looking mate, I spent best part of this year waiting for a good price on it.
after the bounty and no good prices around now
City has been just under £200 several times this year. £195 I think the cheapest so far. £99.99 might be a little optimistic - it's a great set. I did get it for just under £97 a few weeks back, but that was a combination of Paypal codes, VIP points, selling free gift sets, Topcashback and O2 code!
Camel3 shows this has been at £137.99 on Amazon, I think this could drop to £99.99 next year, I also think we could see the City set at £200 too.
