We are paying $45 per site for eFrequency, and $45 per site for eCards. No per transaction fees.
The setup was all done by Radiant dialing in via PCA, at least for us. There were no dealer setup fees. The cards for both apps do get purchased through your dealer and there is a setup fee for the initial artwork. The cards, I believe are roughly between $0.50 and $0.60 per card if you are buying at least 5,000 per order.
You can use the same card for the eFreq and eCard, which we did when we first started. We recently split into separate cards for each program due to requests from our service team and guests.
