I feel kind of dumb asking this but I can't find an answer anywhere. I just got my survey for a $25 dollar pledge and wanted to add things (the extra book for $30 and a patch for $4) but the survey asks all of that in past tense (i.e. "Did you add a book for $30). So did I somehow miss a step and lose my opportunity to add those things, or do I just need to check the items and then I'll get charged the extra $$ for them?
