I have the following XML that I need to shred into multiple tables. Also is the query I am trying to apply. The problem is that I need to Include the OfferId In each of the tables and the commonality. When I try to use the cross apply method I get back way to many rows for one offerId. I am getting back about 139 rows for one offerID when there are only two sets of terms related to this one offerId.
Any help would be appreciated

Perfect. Thank you.

You're shredding the same document twice when you really don't need to, because you started from the highest relevant point in the document hierarchy and worked down, when you really should start from the lowest relevant point in the hierarchy and work up. You don't need the cross apply at all.
SELECT fr.value('(../../offerId)[1]', 'int') AS offer_id,
fr.value('(internetPrice)[1]', 'decimal') as [internet_price],
fr.value('(newStandPrice)[1]', 'decimal') as [news_stand_price],
fr.value('(canadianPostage)[1]', 'decimal') as [canadian_postage],
fr.value('(foreignPostage)[1]', 'decimal') as [foreign_postage],
fr.value('(issues)[1]', 'tinyint') as [issues],
fr.value('(months)[1]', 'tinyint') as [months]
FROM @feed_subscription.nodes('/Offers/Offer/offerTerms/term') AS s(fr)
If you do want to use the cross apply then you should use a relative path not an absolute path.
select
b.value('(offerId)[1]', 'Int') as [offer_id],
fr.value('(internetPrice)[1]', 'decimal') as [internet_price],
fr.value('(newStandPrice)[1]', 'decimal') as [news_stand_price],
fr.value('(canadianPostage)[1]', 'decimal') as [canadian_postage],
fr.value('(foreignPostage)[1]', 'decimal') as [foreign_postage],
fr.value('(issues)[1]', 'tinyint') as [issues],
fr.value('(months)[1]', 'tinyint') as [months]
from @feed_subscription.nodes('/Offers/Offer') AS a(b)
cross Apply b.nodes('offerTerms/term') as s(fr) -- relative path

Try this:

fr.value('(newStandPrice)[1]', 'decimal') AS [news_stand_price],

FROM @feed_subscription.nodes('/Offers/Offer') AS a (b)
CROSS APPLY b.nodes('/Offers/Offer[1]/offerTerms/term') AS s (fr) ;
This returns incorrect results. It always returns the terms for the first offer rather than the terms that correspond to the current offer.

Thank you. I actually like the version not using cross apply.

Thank you. I actually like the version not using cross apply.
... until you test both versions against a larger XML file...
Your preference may change 😉

The OP probably didn't look closely enough at the results to notice.

I'm assuming the OP is me but what does it stand for? And I hadn't checked the actual data yet only the counts.

Sure, nor did I obviously 😀
I am trying to further this example to learn how to present multi-level XML structures using APPLY. I created a new topic here http://qa.sqlservercentral.com/Forums/Topic1072972-338-1.aspx since it seemed different enough and I have already caused enough trouble on this thread. Any help would be much appreciated.

So I am obviously not understanding something, I tried to apply the same logic to this query and I am getting null back for the OfferId. What am I missing?
SELECT distinct fr.value('(../../offerId)[1]', 'int') AS offer_id,
fr.value('(crossCombOfferId)[1]', 'tinyint') AS [cross_combo_offer_id],
fr.value('(magazineId)[1]', 'smallint') AS [magazine_id],
fr.value('(magazineName)[1]', 'nvarchar(500)') AS [magazine],
fr.value('(sourceKey)[1]','varchar(255)') AS [source_key],
fr.value('(offerTerm)[1]', 'tinyint') AS [offer_term],
fr.value('(offerValue)[1]', 'decimal(9,2)') AS [offer_value],
fr.value('(canadianPostage)[1]', 'decimal (9,2)') AS [canadian_postage],
fr.value('(foreignPostage)[1]', 'decimal (9,2)') AS [foreign_postage]
FROM @feed_subscription.nodes('/Offers/Offer/CrossMarketingOffers/crossSells/CrossSell') AS s (fr);

I was able to get it to work using the cross apply method
