Somehow I got the wrong size socks for my daughter but it was too late by the time I discovered it. They are now sold by size but I could swear when I ordered them they were by age... I could be wrong. Also I wish it were easier to find the vouchers on at the moment. I"m not on Facebook. Every time I order I have a feeling there is a voucher on but I don't know where to get it or find it and that makes me feel that I'm overpaying yet I'm a repeat customer. I want to make an order now but I'm going to email you guys and ask if there is a voucher for black friday (weekend). ..
