As I don't have vast research to do, I have used Pay-as-you-go to access this site. This has been fine, untill recently when ancestry seemed to have stopped access to records previously saved to your shoebox, after all your credits are used.
As I have already payed to view these records IN THE FIRST PLACE, I think its very greedy of them to charge again if you want to view records previously payed for, and saved to your own shoebox. In the past this was not so. This is a recent change for the worst. So it now means every record you may wish to keep, needs downloading. BE WARNED! If accessing via Pay As You Go.
