### sample discount object:

id : whatever product_ids : [] count : 123 needs_verification : true/false discount_percentage : discount_amount : origin_cart_id : whatever pending_verification : [cart_id => date_time] used_by : [cart_id => date/time]

other_fields will be added from owner_concern.

*if both percentage and amount are present, then amount will be used.

*when a payment is made => check if cart fully paid => show option to create coupons,enter discount amount/percentage,enter needs verification or not => if yes => create a discount_object with those details

*now when someone finds this discount object => give link to create a cart directly with it,(there should be an action on cart_item called bulk_create => there will first create the cart items => then redirect_to create_cart => with those cart_items, and also the discount code)

*now in prepare_cart => if dicount_code is provided:

1. check that the code id exsits

2. check how many have been utilized

3. if verification is necessary then send a message to the verifier, or in case the cart is being proxied, then the verification is bypassed => when he updates the discount object as verified(for that user id)

4. if verification is not necessary , add the user to the discount object -> as those who used this.

*now if no verification is needed or after verification incorporate the discount_amount in the calculation of the cart_price.

*show the modified cart price.

*let him make a payment, he can make with amount as 0, with cash. gateway payment is disabled if pending balance is 0.

*the payment is instantly accepted if pending_balance is zero.
