Leo is usually great with money, due to their Sun ruler. They know how to find the best deals, and usually luck into great financial advice from their wide circle of friends.
Making even more money depends on reining in spending. The one area Leo could use help in is laying off the credit cards. You love to make splashy purchases and have to look great at all times.
The best bet is to stick to the bargain rack, or search for what you want at a discount. Saving money now means more fun tomorrow!
