I didn't see anywhere any statement by Godaddy if they will increase their prices tomorrow (most of registrars will). I guess they won't increase their listed price, which at $10.19 is high already, but I also guess that $7.15 domains (using coupons) might be gone as well (since it's not profitable for them anymore). Anyone has any ideas?
The coupons will remain valid, they are the cornerstone of GoDaddy's online marketing. As of this minute, the .com's still seem to be at the old price.
I think renewing existing domain name for multiple years would save on cost if there are chances of price hike in near future.
