• Does a purchase on Vinted count as a second hand purchase?
• Does a single second-hand purchase during the challenge validate the challenge?
• Does buying a book count as a new item?
• Does buying sewing fabric count as a "new item"?
• I have put money into a friend's money pool to buy him a new item. Can I still try to validate the challenge or does that invalidate it?
• If I buy something new in order to fix something else, what then?
• Do I need to include every member of my household in this challenge?
• If my only spending is a gift (a pair of handcrafted ceramic earrings), can I validate?
