My kids love playing with toy cars, and they have quite a collection, however this is a bargain that's hard to pass up. Amazon Seller My Blue Cloud Shop are selling a pack with thirty-six metal die cast cars for just £4.49, and there's even free delivery included.
This would be a great gift for any birthdays coming up, or even to split up for party bags. This price works out at just over 12p per car and I don't think I have ever seen toy cars for such a cheap price.
These aren't going to be the same quality as Hot Wheels cars for this price, and the reviews are certainly mixed, but these are a cheap alternative.
If you don't need quite so many cars there's also a set of 8 for £1.49* with free delivery.
