Until now, I still haven't decide if I should get them or not. 

I have That Summer Concert & Second Invasion Concert videos in my phone already and I have been watching them. I love it!! I feel like buying the DVDs not only as a collection but also as a support to Infinite. (I know it's pretty late though) But there's also a feeling telling me not to. That's why I haven't get them even until now...

I haven't watch their Infinitize showcase. 

Please tell me more (Abt That Summer Concert, Second Invasion Concert & also the Infinitize Showcase) I really can't decide ):
