A record number of fake goods are being sold across Europe.
Pirate copies of brand-name clothes or toys can be dangerous as they don't go through the same strict safety checks as the genuine items.
The quality of copied DVDs and CDs can also be pretty rubbish, but they're not always easy to spot. So have you ever been fooled by a fake?
Have you ever bought something thinking it's the real deal, only to find out it's a poor imitation?
Maybe you've been given something that turned out to be a copy? Do you think
anything would stop people selling fakes?

"No, I'm really aware of fake and real things. I can tell straight away if something is real or fake."
Eleanor, 13, Ireland
"Fake goods are horrible. The majority can harm your health and the fact is is that they do NOT last, they are ill-made and they break easily."
Natalia, 12, New York, USA
"Fake designer clothes and bags are often really bad quality. I would only buy the real thing. There are lots of fake Louis Vuitton bags everywhere and they are really cheaply made."
Mi, 14, Lincoln, England
"I actually support the makers of MOST fake goods - not the ones who spend the profits on drugs, though. By buying fake goods you are allowing the little man to live - and if you don't have the money to burn on a £50 top then the £5-10 fake is worth it - major corporations are rich enough, why add to their ill earned gains?"
Emma, 12, Gateshead, England
"If you go to a proper shop you know you're not going to be ripped off."
Tom, 13, Stoke, England
"Fake clothes are good because they're normally way cheaper than the real thing and some other things can be good too. They save you paying a fortune for stuff, though fake DVDs, CDs, games and stuff like that are really bad!!"

"I think that all fakes are rubbish!! Once I went to a market, and I bought what I thought were real Ugg boots, but when I got home, my dad looked at them and told me they were fakes! I was really upset, because they cost me £30, but my dad took them back to the market the next week, and the stall was still there, so I got my money back."

Adam, 12, Solihull, England
"When I go on holiday to Europe, there are loads of people trying to sell fake goods. Most of the time the clothes aren't good quality and things like CDs, DVDs and games don't even work. You can often tell by the quality and the price."
Charlotte, 13, Peterborough, England

Kaleem, 11, Worcester, England

Haidar, 15, Manchester, England
"It's disgusting that people are getting ripped off. If people get caught they should get arrested. On the TV there was a man selling laptops but it was water in a cheap laptop bag!"
Alice, 12, Bedfordshire, England
"I think fake clothes are OK but games, movies and CDs are not because you've spent money on them and when you reach home if they don't work you get frustrated, and you have just wasted your money."
