Should I?

After purchasing three Balenciaga bags in the past few months,  I came across the Mulberry Oversized Alexa Satchel.  Then I just read The BagHag Diaries about this bag this morning.  I'm really trying to decide if I should get one.  I seldom use my Balenciaga bags.

I want the black Alexa if ever I will get it.  Ho-hum...Should I or Should I not?
