The truth about Frozen Yogurt

I own a self-serve frozen yogurt shop. I have 10 flavor options.
Only one flavor has cane sugar in it. The rest has either high fructose corn syrup or Splenda (no sugar added option for diabetic people)

Does it bother you?

well if you've been going to self-serve froyo shop, I guarantee you've been getting a yogurt with high fructose corn syrup.

Most shops use the yogurt that comes in a carton that you can just thaw it and pour it into the machine. my competitors, they all use the same yogurt from couple different companies.

I actually found out about the ingredients few months after I opened my store.

I just assumed, since it's frozen yogurt, it should be healthy.

I tried to look other manufacturers but they all had corn syrup in it.
(I didn't like Splenda either but that was the only option for No sugar added)
I found one manufacturer though, however, their yogurt is more expensive.
I can also buy powder mix and mix it with plain yogurt & flavoring.
(this is hard when you carry many flavors)

Here is the thing. I can only make fruity flavors. People love sweet flavors like cake batter, caramel, cookies and cream etc. I can't make that. No manufacturers make it with cane sugar.

So what are my options?
A: Serve those yogurt just like everyone else. Keep the cost down. Keep my mouth shut about corn syrup.
B: Put all organic flavors. Charge 49 cents per oz (40% more expensive to get it) and expect to see a lot of people flipping at price and leave the store.
When they ask why I don't carry flavors like cake batter, tell them 'it has corn syrup in it, I can't sell that in my store'. Watch competitors taking your customers away

I am frustrated because I think people won't pay higher price for better quality yogurt. But when they find out it has corn syrup in it, they will get mad??? Who expects good quality at Walmart? Can you imagine someone getting mad for a price of organic farm raised chicken at wholefoods because it's a lot more expensive than chicken at walmart?
Am I making wrong assumptions?
Are there a lot of people who would pay extra for good quality yogurt?
or Most people just don't care about the ingredients but only organic-freaks do?

I tried to carry several organic yogurt and did some promotion with it.
I swallowed extra cost and kept my price at rock bottom (35 cents per oz)
but it didn't go well. I didn't see many people who came because of organic yogurt. so I ended up spending more $ on yogurt that people really didn't care.

Due to competitions, I am going to remodel the store, add some menus and reopen with different concept. I want to build 'healthiest yogurt shop in town' image.

I want to go with Plan C: Out of 10 flavors, carry 4 organic flavors all the time (fruity), 4 sweet flavors (corn syrup), 2 no sugar added (splenda)

I cut price from 39 cents per oz to 35 cents last year because of competition. it was a major mistake since it didn't boost the sales and I ended up giving out 'cheap store' image. I am sure cheapskaters liked it but I don't need those people anyways.
I am going to raise the price back to 39 cents. (over 40 cents will traumatize people)

I have one Big Problem though. Customers will see Organic label on 4 flavors.
what if they ask 'what about other flavors? what's in it? what's the sweetener?'
I really don't know what to do about this.
I don't want to bash other business by saying 'well at least 4 flavors are organic, guy down the street has all corn syrup based yogurt'

To conclude, I can't make all organic froyo store. but I'd like to offer some at very fair price. I am concerned about organic options creating bad effects on rest of flavors.
what's your suggestion?
