Showing item-level & order-level offers/promotions on Details page (PDP) &/or Cart page?

I have 2 types of offers (promotions) applicable on my eCommerce website:

  • Item level offers (example: Item belongs to Brand XYZ. Buy any 2 items from brand XYZ to get 30% off)
  • Order level offers (example: $ 10 off on total purchase of $ 100 worth of items)

Journey of user will be: User will go to the Details page of an item, User will see all the item-level offers applicable to the item, user will add the item to the cart, user will come to the Cart page.

Assumption: The user has added 5-6 items in the Cart page, and each of these items has 2-3 item-level offers associated with it, and there are 2-3 order-level offers applicable too.

Question is:

  • Where should I list the item-level offers associated with the item?
  • Where should I list the order-level offers?

Possible options:

  • Showing item-level offers only on Details page
  • Showing item-level offers only on Cart page
  • Showing order-level offers only on Details page
  • Showing order-level offers only on Cart page
  • Showing item-level offers only on both Details page & Cart page
  • Showing order-level offers only on both Details page & Cart page

How ‘AND’ and ‘OR’ can be combined in advanced twitter search operators?

I want to find tweets including one of these three possibility in search results:

  • AAAA” and “BBBB

or

  • AAAA” and “CCCC

or

  • AAAA” and “BBBB” and “CCCC

I mean that AAAA should be in tweets results and one (or both) of BBBB and CCCC should be included too.

How AAAA, BBBB and CCCC should be arranged using one AND operator and one OR operator to get the described result?
