Not an Amazon wish list but an app where anyone in a group can log on, list their preferences for birthday or Christmas presents for the year and see everyone else's, then tick off when they've bought sonething for someone else in the group. Hope that makes sense!
In my family some of us buy presents throughout the year, others leave until the last minute but we'd all like to buy things that are really wanted this year. Looking for an app to organise us all.
