Ben 10 toys may be hugely popular but they are not hugely expensive. Yes, you can buy playsets that cost nearer to £30 than £10, but the most well thought of toys and other merchandise are a lot cheaper. There are quite a few cheap Ben 10 toys on the market, including action figures, watches and clothes. On the watch front, you can sometimes find the Deluxe Omnitrix for under £10 on Amazon. This is the best of the alien transforming devices and offers good role play and mini video game fun. If the price does go over £10, you can still buy the Flip Top Watch in your budget. This is a ‘real’ watch with a digital display but it comes with three lids or tops in the shape of some of the Ben 10 aliens that can be swapped out to add some fun for your child. You can also pick up a few Ben 10 clothes for less than £10. Ben 10 pyjamas are a good bet to send your child off to bed in an alien hero mood. You can choose between shorties and full length versions as well as many different designs.
