Sorry technical people but worlds biggest technophobe needing help yet again. Grandchildren having an ipad for Christmas but their parents haven't bought them any apps to go with it. I have a list of suitable apps but have no idea how I go about buying them for them. I mean, can I just go to a shop and buy them or is it an internet thing? I just don't want the kids to have an ipad on Christmas day and nothing to do with it. Thanks in advance [sorry for my thickness].
