When I bought my boys Lego Minecraft: The Farm, I paid £31 or something for it. You can now get it for £20 from Amazon or Tesco Direct. Amazon include FREE delivery and Tesco Direct have it included in Clubcard Boost. That means if you have just £10 in Clubcard Vouchers you can get it. If not then perhaps Amazon is the better deal for you.
The Lego Minecraft: The Farm set consists of 262 pieces and includes a Steve minifigure, a skeleton, cow and sheep. You also get a crafting table, a pumpkin helmet, two torches, some fence panels, waterfall, sugar cane, pre-mature and mature wheat, carrots, trees and MORE!
Should you choose to buy Lego Minecraft: The Farm from Tesco Direct then you can opt from their FREE Click and Collect service. This means no waiting in for deliveries, you can just go pick it up at your convenience from a Tesco store near you.
