Urgent domestic flight ticket booking help and suggestion needed.

[telescope]

I want to book domestic return flights on indigo.

1. There will be 3 passengers. If booked in one PNR, and seat is not bought, then will the seats get alloted randomly, or side by side?
2. Which website is offering lowest prices / or running some good promotional offers right now?
