Note: The usage of "almost every Wednesday" here is ambiguous. It's unclear whether it's meant to include or exclude every Wednesday. I can see a reasonable disagreement. But the point is that it doesn't matter. The LSAT does not trade on the kind of ambiguity that gives rise to reasonable disagreements. See, if you want to interpret inclusive, then that's how the video lesson does it too and you get to the right answer choice. By default, you are taught in the Core Curriculum to interpret "most" inclusively.

Now what if you want to interpret exclusive? Okay, let's do it. You'll see that this won't change anything about the right or wrong answers.

Exclusive interpretation of "almost every Wednesday is a free poetry reading day" means that it does NOT include every Wednesday. In other words, on some Wednesdays there are no free poetry readings. Okay, so let's translate this to:
W -(e)m-> free poetry reading -> 1/2\$ coffee

"-(e)m->" means "exclusive most" as opposed to
our standard "-m->" which means "inclusive most"

Therefore, what's the relationship between Wednesday and 1/2\$ coffee?
W -(e)m-> 1/2\$ coffee or
W -m-> 1/2\$ coffee

I mean, we know most Wednesdays are 1/2\$ coffee days. Really the question is whether we can say for sure that there are Wednesdays on which Zack's does not offer 1/2\$ coffee. You might say, well, we do have some Wednesdays where there are no free poetry readings. Okay. And on those days... what's the price of coffee?

We don't know. They could well be 1/2\$ coffee for some other reason. Because it could well be that Zack's is just crazy about offering 1/2\$ coffee all day every day. Because Zack is just a great guy.

Even under the exclusive most interpretation, what (D) says still Must Be True. Zack's offers 1/2\$ coffee all day on most Wednesdays, possibly all Wednesdays. Indeed it must be true that it's possible. Answer (E) is still at best a Could Be True. We just don't know that there are some Wednesdays on which coffee is more than 1/2\$.
