Go to any shoe or leather coat store (like Aldo, Wilson's Leather, Bakers Shoes) - they sell "leather & suede protector" spray. I have it and it always works - you just spray your shoes, or bag down and you're good to go. HTH!
I love the Apple Garde stuff... I use their leather protector spray and the conditioner. You can usually get it at Burlington Coat Factory for like $5.
