Is there anywhere I can buy a discounted 1 day ticket?

[tooh8ful]

My daughters and I are going to WDW for 2 weeks in October using 10 day MYW tickets. I have 2 single day comp tickets from a miserably rainy MNSSHP years ago. We have a couple of days of wiggle room in our travel time and I don't know when I'd ever use a single day at WDW. SO, I was thinking we could add 1 night at our resort and buy a ticket for my youngest daughter (8) and hit MK one more time.
I've looked at several of the reputable ticket sellers and their one day tickets actually have convenience charges making them higher than Disney. Am I on a wild goose chase? Should I just plan on buying the extra ticket at WDW?
TIA

In a word: no. Just buy it from disney.

So far I found if I buy discount GC and buy from Disney will be our best price. My husbands union offers tickets but the one day is just as much as Disney once you add shipping.

There are no discounted one day tickets. Buy at Disney.

The only place that offers discounted one-day tickets is USSSA. They use to be available to anyone, but they seem to have limited access to people participating in their events now.

How about using a target credit card and buy disney gift cards [ 5% discount] and use them to buy the 1 day tickets in disney.

Thanks everyone for your help. It's funny, so far I've paid for 90% of our trip with discounted Target cards (you should SEE the stack in my desk drawer) yet it didn't occur to me to buy the extra ticket that way! That is the route we will take. Thanks again for your help.
