Why discount cap is important

Discounts on Flipkart's Big Billion Days purchases is available on eligible Axis Bank and ICICI Bank cards. The word “eligible” is important here.

Banks often exclude corporate cards from such offers, and the discount can also differ depending on whether you make a regular card payment or opt for EMI, according to a blog post by Card Express.

Flipkart and the banks have not yet published the full list of exclusions for this sale. The same applies to Amazon, where the complete list of exclusions for the card offers is yet to be disclosed, the post noted.

The discount cap is also important. “Up to 10%” does not mean every eligible purchase will get a full 10% discount. The maximum discount in rupees will determine how much you actually save. Flipkart usually displays this cap on the offer banner at checkout rather than announcing it beforehand.

If the cashback benefit is described as “unlimiated”, it means there is no maximum cap on the total cashback you can earn over multiple purchases, subject to the card’s other eligibility and spending conditions.
