K-Pop shops based in US?

Anyone know of any good online shops that ship from the US?

I'm christmas shopping for people and the overseas shipping is murdering me :/ I've been perusing a couple places but I want to know if you guys know of any good ones too.

Also, I very specifically am hoping to find a tie with some kpop things on them. Super Junior/Exo is preferred but anything works. I saw some a longgg time ago, but am having hell finding a place with them again.

Let me know if you guys know of anything. Please and thank you!
