I don’t know how stores make ordering decisions, but I strongly suspect that being able to sell off animal products at a reduced rate would disincentivise more careful or conservative ordering of those products—they’ll make back the cost either way, and the potential profit would likely make the risk of needing to sell some items at cost price seem worth it. I think freeganism is a pretty solid idea, but only in the sense that does not require the purchasing of any animal products e.g. eating non-vegan leftovers after a family Christmas that would be thrown away otherwise. Buying vegan products is almost certainly worse overall (for the environment, for example) than just eating food that would otherwise be dumped.
