The Lego Duplo Number Train is on special offer at Amazon right now, reduced from £13.59 to £9.00.
Unsurprisingly, since everyone seems to LOVE Lego Duplo, the reviews on this item are pretty spectacular. Out of 107 reviews, a total of 96 customers have rated it the full 5 stars. Here's a fairly typical comment from a customer who bought one:
"Great quality from Duplo as ever - you can't really go wrong with this. It's colourful, appealing educational and young children just seem to love it. The children in my family 15 months to just over three years all enjoy playing with it. It's hard to find a toy that's not a one minute wonder these days and not total rubbish but this is just great."
It's suitable for little ones aged between 18 months and five years, and it's basically a toy train made out of Lego Duplo bricks, which you can rearrange to build other constructions including a dog house or tunnel. There are 10 numbered bricks included so it's an ideal toy for any little person getting to grips with numbers.
Delivery is free if you're a Prime customer, otherwise you'll probably want to add something to the value of £1 to your basket so that you won't be charged for postage.
