They do have quite a bit of kpop groups merch but I can renege specifically if Big Bang was one of them. There's also lots of surrounding stores that sell merch if you want to check it out. Sorry I'm not much help.
Very little. I freaked when i found a Kwon Ji Yong/GD keychain/strap last weekend. It's still a great store and they have lots of fun stuff, just not a lot of 2nd gen merch.
