You may only buy what the Merchant currently owns:
[Please note: If you summon the merchant far from a place like Ferador (In Cuspia, for example) they may not be so generous with the pricing of items that have come from Ferador. Keep locations in mind when haggling. The Merchant buys back at 50% of the original cost.]
Cost in gold is on the right.
