Mango Savings - 6.00% APY For Up To $5,000

I first reviewed the Mango Savings Account in March 2011 when the yield was 5.10%. The yield has actually gone up to 6.00%. However, it applies only to balances up to $5,000, and it's only a promotional offer.

This Finance Buff blog post has a good review of how savers can take advantage of this Mango Savings Account. As I described in my review, these savings accounts from prepaid card companies have many potential gotchas.

Have you tried Mango, NetSpend or other savings accounts from prepaid card companies?
