Beware!!! You would think that when you upgrade to one of the offers that they would turn off automatic renewal on the old product. Well guess what they keep charging you... I bet they are well aware and love the little extra they are getting. MAKE SURE YOU TURN THE OLD PRODUCT OFF FROM AUTO RENEW.
Also if you upgrade part way through your subscription they owe you a bit of money. Again you would think they take this into account when billing your upgrade, well again a little extra goes in thier pocket...
BEWARE!!!
