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 causes Link to be called a thief by Trill every time he comes near the shop, basically meaning stealing something will make that shop inaccessible for the rest of the game until Link pays Trill appropriately.
It is also possible to pay too little; and this results in Trill saying the payment is "on the skimpy side". However, Link is still able to shop here after this type of payment. Paying extra or simply giving Trill charity money results in Trill calling Link a generous young man.
