These vehicles with small characters are nice and sturdy for small hands, and don't require batteries. Fun for imaginative play. suggested 18 months - 5 years.
Ocado don't have the full selection but the ones I've checked are cheaper than Amazon.
eg. Richie Race Car 7.99 (9.99 elsewhere)
the Palace Guards 7.99
Police Boat Perry 7.99 (can be used as a bath toy)
they're selling individual figures for £1.49 but they're lucky dips (2 options each with one of 4 characters in). the sets come with 1 or 2 anyway.
