If you are already receiving the magazine you wish to purchase then in order for the purchase to go smoothly, it must qualify with each of these points:

• The current subscription and the one you wish to purchase do not exceed the amount of years offered. 
  • Most publishers only allow 5 consecutive years for any given title. If you exceed this limit your order will be rejected.

• You enter the shipping name and address exactly as it is stated on your current subscription.
• Entering it differently can and probably will result in receiving multiple issues each month.
