A product has a monthly recurring charge (MRC) with different rate tiers valid until Dec 6, then starts another different rating tier after Dec 6.
When the product is purchased, the user observes that the rate tiers are applied correctly from Dec 4 to Dec 6 and a different rate for Dec 6 to Jan 4.
There is a discount which applies 50% discount on the MRC, which is purchased from Dec 4. The user observes that the correct discount is applies for Dec 4 to Dec 6, but for the period Dec 6 to Jan 4, the discount is applied twice.
