=== Selling Evolution Stones ===
'''Evolution stones are worth more as money than for evolving Pokémon early game.''' This may seem counter-intuitive, since Evolution Stones let you collect even more Pokémon. But in the early game, you find a lot of Pokémon very fast, and most of them are going to level up through EXP rather than evolution stones. You can begin using stones on Pokémon once you own Dive and Scuba Gear.

'''Evolution stones are always available in the Poké Mart for $2,100 as well as from the Silver Daily Prize.''' Making $2,100 will be much easier once you own HM08 Dive and Scuba Gear, and the Silver Daily Prize can be earned by clicking 500 Pokémon in one day (which isn't too much of a time investment if your loading speed is good.) 

'''Evolution stones and evolution items are not quite the same, though.''' Evolution items come in a wider variety, only evolve one or two species of Pokémon, and are in general harder to find. Both stones and items cost $2100 in the store, but you may want to save the items since they're harder to get for free.
