Endicia: maximum postage purchase: $500 (your account can only have $500 at any time)
minimum postage purchase: $25
If you would like to set up your account to automatically purchase postage when the balance in your account reaches a certain limit, please follow the instructions outlined in our forum post here. Additionaly, if you wish to increase your account limits, we advise you to contact Endicia directly at support@endicia.com.
