What to watch out for when buying toys online
HERE are the British Toy and Hobby Association's top tips for buying toys online:
- Shop early. Don't leave purchases to the last minute rush which might leave you fewer options of where to buy from.
- Check out third-party sellers. Look for sellers you recognise and trust. Be cautious of retailers you don't know and do your research checking reviews and where they're based.
- Go for branded toys. Try and choose a branded toy as then you can compare it to the manufacturer's own website to check it's legit.
- Be careful of going for the cheapest price. If something looks too good to be true, it probably is.
- Check if there are any age restrictions. Make sure you give suitable toys to children based on their age.
- Check reviews carefully. Some reviews are fake so look carefully at the comments.
- Stay with children at first. When your child opens a toy for the first time, stay with them and check for faults, detachable small parts, access to stuffing and loose or accessible batteries or magnets.
