One reading a day is free. Credits are for when you want more than that, and they do not expire.
More cards means a longer and deeper reading. The ten-card spread reads the situation from inside and out.
The more you take, the less each one costs. Nothing expires.
Unused credits are refundable within 7 days of purchase.
When does the free reading come back
At midnight in your own time zone, not ours.
Do credits expire
No. Once bought, they stay until you use them.
Do follow-up questions cost credits
One follow-up question is included with each reading. Beyond that, each question you ask uses one credit.
Can I get a refund
If you have not used any of the credits you bought, you can have a full refund within seven days. If you have used some, you can have a refund on the remainder.
