Free Luxury Balls and more!!!
After beating the Elite 4 and do the Celio mission, go to Five Island and surf up to Resort Gorgeous. Go right and into the lost cave. Save Lady Selphy and after that, go see her in her house. She will say she is bored and will request to see a Pokemon. Go back to Five Island and get that Pokemon from the PC and put it into your party. Go back to her house and she will get her butler to reward you. He will give you: Luxury Ball, Nugget, Pearl, Big Pearl, Stardust, Star Piece and Rare Candy. The hardest items to find that she'll give you are the Luxury Ball and the Rare Candy. The others you can sell for tons of money. I got 20 Luxury Balls, 2 Rare Candies and $10,000 worth of sold items.
