How can I be sure that 2 people don’t buy the same thing?
When someone comes to buy an item from a gift wish list, they must click on the “I’ve bought it” button once they have completed the purchase. Once this is done, the gift item is removed from the online gift list to avoid duplicate purchase. The gift wish list owner will always see what has been bought from their gift wish list, until they choose to delete the item or the list.
