RootsIreland's offer for viewing free search result pages in July has now been extended to the end of August.
The extension has not made the offer any clearer, however.
In summary, the standard offer is that new researchers can view 10 free Search Result Pages after registration. Once those 10 freebies have been used, you have to pay to buy credits to view each page of search results.
Under the offer terms you can view Search Results Pages at NO additional charge based on the number of unspent credits in your account at the time the search is performed. The 'free' credits will expire when the offer ends.
