yes, these are subscriptions, so that must be the issue. i didnt realize this was a common issue. thanks for the quick reply.
is there a way to handle Ad packages on the same zone with different durations? I have an ad zone that i would like to have 1 month, 6 months, and 12 months offerings that are discounted. The only way I see to do this is setting up 3 different ad packages for that zone. unfortunately, if someone purchases 1 month, the 3 month is still available. There may be an easy way to handle this that I am not aware of as I am new to openx.
