Wares and Prices
Trill's Shop owns a rather unique method of payment. In order to pay, Link must pay the written amount of rupees into a box. Because of this, Link can steal products with relative ease. However, doing so will ause Link to be called a thief by Trill everything he comes near the shop, basically meaning stealing something will make that shop inaccesable for the rest of the game.
It is also possible to pay too little; and this will result in Trill calling Link a cheapstake. However, Link will still be able to shop here after this type of payment. Paying extra or simply giving Trill charity money will result in Trill calling Link a kind man and encouraging him to return.
