An example I tried was a $35 entertainment coupon V.S. discover $40 voucher, my total rental payment was actually the same, with Discover lower by about 20 cents instead of $5. Why waste your $20 Discover credit on this when you can get entertainment codes on this site for free and the difference is only 20 cents? Use your Discover credit on something else that's worthy.
I can't find any $35 Entertainment coupons good for one day (or short) rentals. Are they only good on longer rentals? Also keep in mind, it only takes $20 of Discover cash credit to get a $40 National coupon.
