Exactly, thats really what makes me mad. They could have at least said, sorry I am not interest anymore, or I can't afford it right now or whatever the case is. Not simply ignore invoice, and multiple reminder for entire month. I mean, I can understand things come up or change your mind about something. I have done so in groupbuy myself couple time, but I always contact to the organizer. Also if the buy was hinging on success on my order, I would try my best not to cancel if I could afford it. But that's me I guess.
