I have used the eSignature the past 2 years.  I have learned to use the 5 free ones in the current year and then buy more.  I use all five before I buy.  I'm sorry you experienced that problem.  Makes me think to continue using the same process next year so I don't lose the free ones.  I do know that the eSignature purchases do not carryover to the next year so I am very judicious at the end of the season in how many I buy.
