Baby cereal, jar or mix?

I've noticed a lot of controversy on this topic.

As far as I'm concerned,  what is the problem with the added convenience of ready to eat cereal? Same manufacterer, I'm pretty sure it doesn't matter if u mix it yourself or you buy it mixed, there's no big difference in ingredients. The only downside is your not getting the added breastmilk for mixing, but rather the formula or juice they use for mixing.

For two cereal with fruit meals a day, it was costing me about $2 a week for boxed cereal ($8 mo) and $5 a week for 7 jars of fruit, ($20 no) split in half for each twice daily feeding, for a total of $28. Which would technically be more if I had to buy juice or formula to make the cereal, but i use breastmilk.
Which is turn requires mixing, adjusting to get the right texture, heating, and washing a bowl.

For two cereal feedings a day, one plastic rectangle container or one jar lasts for two feedings as she only eats half. So one 2 pack of rectangle containers, is $1 at pricechopper. Theres a great variety of oatmeals, and mixed rice, granola, etc with all different fruit combinations.
$1 is 4 meals or 2 days. 30 days in a month, is $15 cost to have premixed, always the same texture and amount, room temp, no bowl, and ready to take with you or keep in the diaper bag when your on the run.
Even moving up to three a day, still keeps this cost at 3packs/two days to about $20.

So yes, I buy jars/containera and pay for convience, but it also saves me money!

Six month update.

Ok, well actually 5months and 17 days.
I never thought I would make it this far, but it is still routine to me, and it's surreal how much it has faded into the background of my daily life. So little effort to reap such big rewards.
Between thanksgiving, black Friday, and Christmas, I was prepaired to be finished with my pumping, as I didn't think my supply would last through the long hour gaps. I was wrong. 7am thanksgiving was my last mercy pump. 5am black Friday, I returned home and out of curiosity decided to try a session. Same result as always, as if I had not almost gone 24 hours.

My schedule now is about 3-5 pumps a day, depending on when I have the extra time to fit in more if I feel it's better for me to do two short sessions rather then one longer session.

Typically I do about 8am when I wake, 2pm after lunch, 7-8 pm, and then 11-12 before bed. But sometimes its more like 11am, 5pm, and 11 pm.

 I no longer count out my ounces daily, but I also no longer have enough to freeze which was intentional as I ran out of freezer space. So I shortened my pumps to about 5-6 minutes. I get about 3-4oz on both sides which is enough for about two bottles which keeps up with her feedings.

At 5.5 months her schedule is in this ballpark, give or take an hour depending on the day.

8am mixed cereal/rice cereal/oatmeal or granola with fruit and a 2oz bottle.

12-noon 4 oz bottle

2:30pm vegetables or a meat&fruit/vegetable mix. 2oz bottle.

4-5pm 4oz bottle

8pm cereal with fruit and 2oz bottle

11 5-6oz bottle

Occasionally she wakes up around 3am and will drink an ounce or two and head back to sleep. Sometimes her daily bottles vary by an ounce, I make them the smaller size and if she wants more I get her another ounce, as if I make her a 4oz bottle with her cereal, she usually doesn't drink it past 2 ounces and 2 are waisted.
