I used to sell on etsy. I gave up when I realised that my genuinely hand made jewellery could never compete in price with the amount of cheap Chinese crap other sellers were passing off as 'handmade'.
It really really irritated me. One seller had dozens of necklaces bought for pennies on Aliexpress, each one in an organza bag with a 'made with love' label and marked up at £20. Etsy of course did bugger all about it.
Not on the high street is exactly the same. Should be renamed 'On the high street in China'.
