Also, take a look a CsQueryOnURL. You'd be surprised how much easier it can be depending on the data you need.
This short guide should point you in a very simple direction:
I'm attaching an example of a semi-long CsQueryOnURL function that returned all the data I needed into separate columns. It's a rough result, but It can give you an idea and make your own calls where you need them.
Example URL: (Might be a dead link at some point, but try it on any url from the same site)
Link to Product Page
Formula: ( Assumes URL is in cell A1, or you replace "A1" with the URL entirely.)
=Dump(CsQueryOnUrl(A1,"title, div[class~=prod-detail] h4:first-child, ul[class=unstyled specs] li, ul + h4, div[class=small] strong, b[class=item-price deal]","",,"text"),TRUE)
