How do I use the value from a 3rd column when comparing 2 columns

[jumpycakes]

I have 3 columns:
A: All Products (text)
B: Sold Products (number)
C: New Products (text)

The Sold Products list is associated with the "All Products" column. I want to know the sales numbers for New Products, so I was thinking I'd compare columns A and C for matches. If there is a match use the B value that is associated to the A column. This number would end up in column D.

Example:

Apples|10|Bananas
Bananas|20|Candies
Candies|40|Apples
Dumplings|70|
Eggs|5|

So the first column would end up as:

Apples|10|Bananas|20|
Bananas|20|Candies|40|
Candies|40|Apples|10|
Dumplings|70|
Eggs|5|

Not sure how I would do that. Alternatively if there's a better solution than the one I proposed, that's fine too.

Perhaps this will work for you:
