The Drunken Lizard Pub

There was this sword with good stats selling at port kuudad, i didnt hd the money and left now i return and there is no sign of it

How do i switch or reset the items that appear on the shop?

i have a bow i can sell and a axe but nobody seems to be able to buy them , they are too expensive

Stores change their inventory every 7 days.

When a store doesn't have enough money to buy your items, you can hope that a store in the last part of the game will have the money since their limit increases from your starting area to the end area.

Buy some cheaper items to increase their money so you can sell the expensive one. Then go sell the cheap ones later or elsewhere.
