...who are the 5 people who willingly chose not to get the best price?
Might not have been 'willingly'...
I found the signup page to be fairly confusing at first glance, and clicked something besides 'Earliest' first. (In a bit of a rush to get in before the 'Earliest' sold out...) I did discover that wasn't what I wanted and changed it, and saw verification of my change.
I went back now, without the rush, and I still think it's confusing...
(We have established that I am new to the crowdfunding presentation... I am supposed to know that 'Pick Your Perk' means "here are the individual items available for purchase..." except that yes, I know, technically it's not an actual purchase, it's a donation with the promise of a reward.)
I couldn't tell if stuff was being bundled (one section kinda seemed like it to me) or what...
Anyway - I can easily see how someone mistakenly selected the wrong option and then didn't notice it at checkout time.
I don't know why those items (like the 'Earlier' selection) are available although sure - you can pledge as much as you want. I think it would have been clearer to simply have the 'best price available at this time' option enabled and make it possible to pledge any additional amount as a separate line item. But I expect that approach requires a lot more processing that the site might not be able to accommodate.
