I'm not familiar with that site either. Are you sure it's not just mirroring the already discounts that are currently being offered? i.e., Online Deluxe and Premier are currently $20 off for a Federal return; i.e., $40 for Deluxe and $70 for Premier. And Self-Employed is $30 off at $90. A state return is $5 off.
These early-season discounts will expire later on in filing season. Normally around March, but TurboTax says prices can change at any time if not locked in by paying in advance.
