@reiver Hmm, the Backer tier starts from $5, but it can be greater than $5. Wouldn't it be enough?

@hongminhee

I suspect most people won't change the amount. They will just choose one of the options.

Also, I suspect, if someone choosing a higher tier, they often do it to get a reward associated with a higher tier. Increasing the amount for a tier doesn't grant new rewards.
