How to express "Now, ..." in Chinese (the usage of "now" to draw attention to a particular statement)? In the following example sentence in English:

Suppose that you buy the product in $10 in the store A. The store A is located in 3 miles away.
Now, you found out that the store B sells the same item in $8. But it is located in 8 miles away.

In this usage of now, an adverb to draw attention to a particular statement or point in a narrative, how can I express it in Chinese?
The most basic word to express &quot;now&quot; in 现在, but I feel it is exclusively used in the situation that specifically refers to the time, not in the way that draws attention to a particular statement.
So what word, or phrase is suitable in Chinese in these cases? Or is it commont to use such expression in Chinese as well, or if not, what is the more natural way to draw attention to a particular statement in Chinese?
Now, you found out that the store B sells the same item in $8. But it is located in 8 miles away.

I am not a native English speaker, but I don't quite agree that now here means draw attention to a particular statement or point in a narrative. In my opinion, it means this sense in this context:

ADV You say &quot;Now&quot; to introduce something which contrasts with what you have just said. 然而
Now, if it was me, I'd want to do more than just change the locks.
然而，如果是我，我要做的远不只是换换锁。

I think there should be an implicit but in your English sentence. So, you could interpret that now as 可是现在, 然而现在，or just simply as 然而，可是.
