Bouncing costs

On August 3 I renewed my account for another year.  Today I got an email asking me to please renew my account as it is about to expire.  To add to the fun I was told the cost would be $39.  When I did renew they charged me $49.  Is this legit or part of their being hacked?  Next year I'm waiting until the last minute to renew.  Maybe I can get it for $29
