Yes (sort of) - I will honor any pledges that come in on or before the bonus dates that we have presented. The backer will get the free corridor pieces only if they convert their $1 pledge into a core set (or more) before the end of the campaign.
If you have pledged the three core set level you can add $90 for additional sets above and beyond the three you have coming already. All stretch goals will apply to this set as well.
