I bought all of them. I mean come on what am I going to do with 9.999 rupees???? I used the discount on the bombs (first play), Fire Rod (HM) and Ice Rod (second play)
I bought all the items eventually... It took a while to raise the rupees though because I spent so much on the Cucco Ranch minigame, and that freaking con artist who I believe was in Skull Woods, but I could be wrong.
I used my discount for the Fire rod, because of the price. Then I bought the bombs immediately after because I use them the most.
I'm going to try a minimalist run.
I'm going to try a minimalist run where I don't buy anything and only rent what's essential.
