hey, i paid for the one month plan illustrator and was charged for it already, but when i go to "my plans" it says that i will be charged again next month. when i tried to cancel the plan (because its clearly not what i paid for) it said that if i cancel it i will no longer have access to illustrator, even though i was already charged for this month.
The annual plan, paid monthly (about $20) is an ANNUAL plan, with a one year commitment (promise to pay $240, in other words). Adobe give a generous 50% discount on the remaining fee for the year if you cancel early.
The monthly plan (about $30) is indeed a commitment of only a month, you can cancel at the end of any month.
