The European Consumer Centre is advising parents to think twice before buying school accessories online in the coming weeks.
It says some websites selling value-for money back-to school outfits may not be what they say they are.
Figures for 2019 from Barnardos revealed that the cost of sending a student to first year in secondary school is around 735 Euro.
The European Consumer Centre says parents purchasing online should ensure the seller is in the EU and make sure to pay through a secure provider.
