Hi there, I see the same question pop up so I thought a little intro to the people not familiar with backerkit would be helpful. "I only want 1 of the books offered - How do I pick the book I want?" If you pledged for a tier with a choice option (so one ebook, paperback book or hardcover book) you pick the one you want in the pledge manager. "what IS the pledge manager" The pledge manager is the survey part of the campaign that comes after the crowd funding part - that's where you make your choices, tell the team your address and add extra things if you want any. Usually it opens up a few weeks after the campaign ends, so people whose pledges fail have time to sort it out. "What about shipping" Shipping is also calculated at the pledge manager stage - we pay that when the pledge manager is "locked" meaning no further changes can be made - up until that point you can change the things you filled out as many times as you like. Usually a pledge manager runs for a while and we get a warning email a day or two before it's locked so we can make final changes. That's the basics I hope it helped some of you make sense of this system. It can be a little confusing your first time.
