Why does Battlefield 4 costs 3x as much on console ? :(

Console games are in general more expensive as Sony/Microsoft need a cut as well. That being said, sales differ all the time, the console versions might be cheap in the future or in a different store.

I've herd that console games cost more because Sony and Microsoft need their cut of the sale, but I don't think that is reason to charge $20 more than PC. 

I checked slickdeals and on 3-22-2016  Premium Edition (includes 5 xpacs and a shortcut kit) was on sale for $19.80 at the Xbox store.  (expired now)

Just saying deals do come around but I feel you on console digital store prices for older titles...

That was a good deal. It is unfortunate I missed it, but at the same time I feel like the game shouldn't even need a sale. I read Battlefield 5 is suppose to release late this year so you would think the retail price of the game would be low without the need of a sale price. :/
