Choice of benefit at Item Level promotion

Promotion That customer want to Provide:-

Buy items of 6995 and above get 750/- off on particular items or get Duffle bag worth of rs.2490 @ 99.
Buy Items of 19995 and above get 2500/- off on particular items or get Duffle Trolley worth of RS.8490 @299

Note:- Customer want item level choice of benefit for above mention promotion.

E.g. I have created two assortments:

Buy Assortment: All Items (Excluding Few get Items).
Get Assortment: Get Items ( Exclusive item DUFFLE Bag, DUFFLE Trolley, Suits/Blazer/Jackets)

Note: All above GET assortment items have a different offer price (e.g. DUFFLE Bag worth of 2490 @99/- & DUFFLE trolley 8490 @299, and in rest items customer like to provide 750 rupee off on each item.).

Now they need to define promotion conditions like:

Buy from Assortment [All Items (Excluding get Items) For Promo] worth Rs. 6995 and above Get 1 unit of Combo [Get Items (DUFFLE Bag,Suits,Blazer & Jackets)].

If the Customer want and select “DUFFLE Bag” then after scanning by the the cashier the system takes the offer price as mentioned in the condition @99/-.
If the Customer selects and want “Suits/Blazer/Jackets” then after scanning by the the cashier the system takes the offer price as mentioned and provide @750/- off.

Buy from Assortment [All Items (Excluding get Items) For Promo] worth Rs. 19995 and above Get 1 unit of Combo [Get Items (DUFFLE Trolley ,All the common items)].

If the Customer want and select “DUFFLE Trolley” then the cashier scans the product barcode, and the system takes the offer price as mentioned in the condition @99/-.
If the Customer selects and want “The Common items” then the cashier scans the products barcode, and the system takes the offer price as mentioned and provide @2500/- off.
