The website implies that on can purchase a set number of credits, as well as pay extra for additional more in-depth searches. What it does not clearly advertise is the incompatibility with iPhones (full info not shown) nor the fact that one has to save and download a search, failure to do so results in using further credits if the same (already paid for) search is revisited. In depth search provided very little extra useful information. Leaving a tab open on the search also allows one to fall into the using credit pitfall as switching between tabs appears to eat up credits as well.
AVOID AT ALL COSTS!!
