Am I wrong for being upset with my wife for making an completely avoidable mistake that ended up costing me almost 400 dollars?

Alright so here is the details, last week I sent my wife out to get gift cards for our nieces and nephews. We do this on years where we can't go see them.. There are 8 of them at 20 dollars each. I asked my wife to specifically go to a specific store, to a specific place in said store to get the gift cards. Which she did not do. Instead she went to a convenience store and picked up prepaid visas which charged and activation fee 20 dollars, and a load fee 10 dollars, and a transaction fee 10 dollars.. So in the end each 20 dollar card cost me 60 dollars.. Or 480 dollars total.. When they should have cost 160. I got angry at her and told her that I was only budgeted for 160, not 480.. And because of that she would need to contribute the difference to our mortgage because I could no longer afford it. And by the way the only bill she is responsible for is half of the mortgage.. I pay 100% of all other bills.. She called me an asshole and told me I was being unfair. If she had followed instructions we wouldn't even be having this discussion..

Am I in the wrong here?
