How to unlock the Penny Pincher achievement in Shovel Knight: Treasure Trove - Definitive Guide
You should have no reason to ever even bother going back to any of the villages. Simply just mash through your new game + playthrough and you'll pop this achievement with no issues.
I can confirm that you CAN turn in song scrolls and this achievement will not be voided because your earning money, not spending it.
It's confirmed you can switch armor's as well so long as you ALREADY BOUGHT THEM.
Missable
Note: As of the 4.0A patch, this trophy can no longer be earned in NG+ so has to be done from scratch in a new playthrough.
The only thing you need to be concerned about is the NPCs that you can pay money to, as this most likely counts as "spending money". The NPCs I'm referring to are the ones in the Armor Outpost in the Fancy Store that each ask for 1000 Gold and the NPC that you have to pay in order to gain admission to the Hall of Champions. Just avoid these NPCs and you won't have any problems. In case you were wondering, refilling the Troupple Chalices is okay, as it is free and doesn't cost any money to do so.
