Tutorial:NPC Flipping

NPC Flipping is an act of reselling items bought from NPCs or Bazaar for a higher price. NPC Flipping is a good way to earn money early to mid-game with a little effort.

Part 1: NPC => Bazaar
When people say "NPC Flipping", they usually refer to this. Most of the time NPC item selling price is lower than a Bazaar selling price. That means you can actually buy items from NPC and sell these items to Bazaar for a higher price. This method can give you about 100k coins daily.

Check for prices
Check for the selling price on Bazaar before buying said items from NPC. Some items have a higher selling value from NPC than selling value of Bazaar.

Common example is Ghast Tears. Ghast Tears can be bought from Alchemist for 200 coins, but are usually sold at Bazaar for only 30 coins.

Sand on the other hand can be bought from Farm Merchant for just 4 coins. The average Bazaar selling price for Sand is about 12 coins. About 6000 coins can be earned on reselling sand alone.

Have enough inventory space
All the items that are sold by NPCs and can be sold to Bazaar have a selling limit of 640 items (10 stacks) per day. In early game, it is recommended to have 30 empty slots in the inventory when NPC flipping.
 * 1) Buy 10 stacks of item A from NPC
 * 2) Buy 10 stacks of item B from NPC
 * 3) Buy 10 stacks of item C from NPC
 * 4) Sell inventory to Bazaar
 * 5) Repeat with other items

Make enchanted items
It is common for enchanted items to have a higher selling value than the unenchanted forms. It can be more profitable to craft items bought from NPC into enchanted items and only then sell it to Bazaar. Please make sure to check the prices before doing it, you might be losing money!

Part 2: Bazaar => NPC
Sometimes prices on Bazaar are smaller than the NPC selling prices. Its called "Reverse NPC Flipping". It usually happens with items that aren't very useful to players but have a high NPC selling value.

Example: Spooky Bait is useless for players that want to catch Sea Creatures. Its NPC selling price is 10 coins. It can usually be found on Bazaar for 9-11 coins (instant buy) or 8-9 coins (buy offer). Buying these items in a very large amount could be profitable since you get about 2 coins per sold item. There is no limit on how many items you can sell to NPC, but be careful. Prices can change very quickly.

Items that usually have a bigger NPC selling value: Be very careful with Reverse NPC Flipping and always check prices. Do not place a too high buy offer for these items.
