On the 935 days we compared, Discount Den was cheaper on 910 of them (97%), by $4 on average. Count the days it saved nothing and that's about $4 per one-way trip.
A quick test: divide Frontier's current yearly fee by $4. That's roughly how many one-way trips from Dallas/Fort Worth a year, booked close to departure like these, before the membership pays for itself.
