In Sapphire, if I want something from the Mauville Game Corner, I would grind wild encounters with a team of Pickup Zigzagoon. Selling Nuggets, Potions, and Full Restore would quickly give me disposable poke-dollars to spend on Coins and buy my prizes. But in Emerald, Nuggets are only a 1% encounter, so that strategy won't work.
