Where to Find and Purchase Legit Jerseys

Boys, I got some money from the holidays and I was wondering where you guys purchase your legit jerseys from. I'm from the US and I was wondering if there were any good retro/current jersey shops you go to and what's some of your go to websites for purchasing jerseys.

Additionally, I'm looking for 2 specific jerseys to boost my room decor and I aim to order duplicates: one to wear, one to frame. If anyone know where to find either of these down below please comment or pm me

Barcelona Home Coldplay Edition - coldplay's my favorite band, don't mind barca, like the jersey

2018/19 Manchester United Jersey(POGBA) - Huge Yanited Fan, i'm 16 and Pogba is one of my favorite players and the reason I got into football more , especially united as most of my family doesn't watch footie. I don't care if it's the home, away, or 3rd, but I would prefer the red home jersey.

Thank you all and happy new year
