We offer the option to upgrade either smaller font packages to larger ones, or upgrade single-user licenses to multiple-user licenses. For example, you can buy a single-user license for Fedra Sans Light for €72 now, and upgrade it later to a complete package for the total price of the package minus €72. Likewise, if you upgrade the same font from a single-user license to a multiple-user license, you will be credited the amount you have already paid.
You can also upgrade Extended Latin to Extended Latin/Cyrillic/Greek by paying the difference in price. All upgrades can be done directly from your account: go to My Fonts and click on the Upgrade link.
Either way, our pricing policy is designed so that you will never pay more for fonts even when you buy them one by one. Please contact us if you have more questions.
