Hair affair

So my hair unfortunately isn't this length right now but it was when I first had it cut into a bob so I'm hoping.. preying it grows this length again so I can go for a more pixie lotts looks and even cheat on my short hair with some extensions. 

I'm really tempted to either buy from one of these two sites. Does anyone know any good extensions sites?
