189 * DESCRIPTION:
190 * Different trading posts have different items.
191 * Merchants cannot be cheated, but they can be dishonest
192 * themselves.
194 * Shields, swords, and quicksilver are not cumulative. This is
195 * one major area of complaint, but there are two reasons for this:
196 * 1) It becomes MUCH too easy to make very large versions
197 * of these items.
198 * 2) In the real world, one cannot simply weld two swords
199 * together to make a bigger one.
201 * At one time, it was possible to sell old weapons at half the purchase
202 * price. This resulted in huge amounts of gold floating around,
203 * and the game lost much of its challenge.
205 * Also, purchasing gems defeats the whole purpose of gold. Gold
206 * is small change for lower level players. They really shouldn't
207 * be able to accumulate more than enough gold for a small sword or
208 * a few books. Higher level players shouldn't even bother to pick
209 * up gold, except maybe to buy mana once in a while.
