The way you are saying, I assume that you work or have someone real close (maybe own) that works in a bakery. Not trying to take anyone’s profits away. But most people would recognize that what ever there is in the grocery or bakery would accept it that its before pesach. They will take almost anything, and would still be happy. (So if you have only certain items, you will still get your profits, -maybe even more- nothing gets taken away). Also it should not be relied on the last minute and get rid of it. Then it would be very hard to donate. Just prepare a little earlier or call for a pickup where ever it gets donated. Yes there are plenty organizations that can use it. Look it up.

Of course they need to make a living. But, what happens when the time comes you have to get rid of it? I happened to pass by past year in BP on 13 erev yom tov, there was not a few but lots of fresh bakery stuff spread out. (The “nisht inzerer” were all there). At least donate it to a organization. Not just dump it.
