If you've already purchased an unlock code, then most of the time you'll be able to add additional names later at a discount. Generally however, you'll save more by purchasing the ability to enter more names up front, rather than coming back later to add more names. Here's how it works:
If you purchase a 250 name unlock code and later decide you jump to a 500 name unlock code, you'll pay the difference in price between the 250 and 500 name unlock codes.
Note that the difference in price is calculated at the time you purchase the second code, not the first. In other words, if the price of the 500 name code has increased since you purchased your 250 name code, then the difference in price may have increased as well.
The difference in price is also based on the regular price of the unlock codes, not the sale or promotional prices. So, for example, if you need to enter about 225 names now, you'll save money by purchasing a 500 name unlock code now verses a 250 name unlock code now and a 500 name unlock code later.
If unlock codes for your version are no longer available, then you'll also need to purchase an upgrade to the latest version of ChurchTrac. For exmaple, if you had a 250 name unlock code for ChurchTrac 8, you would need to purchase an upgrade for a newer version of ChurchTrac, since ChurchTrac 8 unlock codes are no longer available for purchase. The price of the upgrade will be added to the cost of increasing the number of names you can enter.
The cost of the upgrade varies based on which version you were using (see the purchase pages for detailed pricing information). Upgrades allow you to get the new features and stability of the newer version at a fraction of the cost of purchasing at the non-upgrade rate. In fact, you may even get a discount on adding names when you upgrade at the same time.
ChurchTrac 9 customers who renew their unlock codes automatically get a discount when adding additional names. ChurchTrac 9 customers with active unlock codes also get free upgrades to new versions as they are released, plus several other benefits.
