PS Vita Games Cheaper on Network

A lot of people ask why purchasing a game through the PSN or XBL is the same price as purchasing the game on a physical disc.  I mean shouldn't it be cheaper if I'm not paying for the case and booklet?  Well for the PS Vita that is exactly what it is.  Some games will have boxed copies and digital copies as well.  Of course buying digital for cheaper is a good idea, if you have the memory space for it.  Considering you can only buy Sony branded memory cards, you'll be looking at spending quite a bit of money still.  So are you really saving money in the long run?  I'm not sure how many games a 32 GB can hold for you, but I can tell you'll be needing several memory cards.  As for me, there is always a place in my heart for media in its physical form.
