Amazon Great Indian Festival and Flipkart Big Billion Days in Oct 2026: Which Debit or Credit Card Can Help You To Save More
By the FinanceChecks.com Editorial Team | Published October 1, 2026 | Last reviewed October 1, 2026 | 7-minute read
Here’s something most shoppers don’t realise until they’re already at checkout: this year, your bank, not your budget, decides which festive sale actually saves you more money. Amazon’s Great Indian Festival and Flipkart’s Big Billion Days are both landing in the same window this October, and each platform has locked in a different bank as its discount partner. Pick the wrong card, or don’t know which one to use where, and you could leave a genuinely significant discount on the table.
Here’s exactly which cards work where, how much each one is actually worth, and which platform wins depending on what’s sitting in your wallet.
The Dates, First
Amazon’s Great Indian Festival opens to Prime members a day early on October 7, then to everyone on October 8. Flipkart’s Big Billion Days follows a similar pattern, with early access on October 8 for Flipkart Plus members, Black members and Flipkart credit card holders, before opening to all shoppers on October 9. If you’re not a Prime or Plus member, the real overlap window where both sales are live to everyone starts October 9.
Who’s Partnering With Whom
This is the part that actually matters, and it’s worth repeating because so many shoppers assume every major bank card works everywhere. It doesn’t, not this year.
Amazon’s confirmed bank partner is SBI. Both SBI credit and debit cards get a 10% instant discount, and this extends to EMI and No Cost EMI transactions too. Separately, the Amazon Pay ICICI Bank credit card, a co-branded card rather than a general ICICI offer, gives 5% unlimited cashback for Prime members and 3% for non-Prime members, with no cap on how much you can earn back.
Flipkart’s confirmed bank partners are Axis Bank and ICICI Bank. Cards from either bank get a 10% instant discount on Big Billion Days purchases. The Flipkart Axis Bank co-branded credit card is listed separately with its own 10% discount as well.
Notably, HDFC, ICICI’s general (non-Amazon Pay) cards, and Axis are not part of Amazon’s offer this year, and SBI isn’t part of Flipkart’s. If you were assuming your HDFC card would work the same way it has in past years, this is the year that assumption breaks.
Card-by-Card Comparison
| Card | Works On | Discount | Known Cap |
|---|---|---|---|
| SBI Credit Card | Amazon | 10% instant discount, including EMI/No Cost EMI | Around ₹13,750 for the full offer period |
| SBI Debit Card | Amazon | 10% instant discount, full payment only | Around ₹9,000 for the full offer period |
| Amazon Pay ICICI Credit Card | Amazon | 5% unlimited cashback (Prime), 3% (non-Prime) | No cap |
| Axis Bank Cards | Flipkart | 10% instant discount | Not yet fully disclosed |
| ICICI Bank Cards | Flipkart | 10% instant discount | Not yet fully disclosed |
| Flipkart Axis Bank Co-Branded Card | Flipkart | 10% instant discount | Not yet fully disclosed |
| HDFC Bank Cards | Neither platform’s confirmed 2026 partner | Not applicable this year | Not applicable |
So Which One Should You Actually Use?
If you’re holding an SBI card, Amazon is where your card does the most work this year, particularly for one or two larger purchases, since the 10% instant discount on EMI transactions can meaningfully soften the cost of a big-ticket item like a phone or appliance. Just watch the cap. At roughly ₹13,750 for credit cards and ₹9,000 for debit cards across the entire offer period, not per transaction, your SBI discount has a ceiling, and large shoppers can hit it faster than expected.
If you’re holding an Amazon Pay ICICI card, the uncapped 5% cashback actually makes more sense for smaller, frequent purchases, or for spending that goes past wherever your SBI cap tops out, since there’s no ceiling dragging it down.
If you’re holding an Axis or ICICI card, Flipkart is your better bet this year, especially for anything through the Flipkart Axis Bank co-branded card, which stacks its own card-specific discount on top of the general bank offer.
And if none of this applies to you, if you’re holding, say, an HDFC card and nothing else, neither platform’s bank partnership is doing anything extra for you this year. You’re shopping on product pricing alone, which is still worth comparing carefully, just without the card-based cherry on top.

The Catch Almost Nobody Reads the Fine Print On
A few details consistently trip people up during these sales, and they’re worth knowing before you add anything to cart.
Corporate cards are routinely excluded from these offers, even when they’re issued by the exact bank running the promotion. The discount percentage can also differ depending on whether you pay in full or choose EMI, so the number advertised on the homepage banner isn’t always the number you’ll actually get at checkout. And because these caps apply across the entire sale period rather than per order, someone making several purchases across the week can burn through their discount ceiling faster than they expect, especially on SBI’s capped offers.
The only way to know for certain what you’ll actually save is to check the live offer terms on the specific product page at checkout, not the general sale banner, since banners tend to advertise the best-case scenario rather than what applies to your specific cart.
Common Mistakes Shoppers Make During These Sales
A frequent mistake is assuming last year’s bank partnership still applies this year, when banks rotate in and out of these deals annually, and a card that worked on Amazon last October might be sitting on Flipkart’s side of the table this time, or not included at all. Another is focusing entirely on the card discount percentage while ignoring the base price, since a 10% discount on an inflated “festive price” can still work out worse than a non-discounted price elsewhere. People also routinely forget that these caps apply across the full sale window, not per transaction, and end up disappointed when a second or third purchase gets a smaller discount than the first. And many shoppers don’t check whether their specific card variant, not just the bank, actually qualifies, since some offers are restricted to particular card tiers or product types within the same bank.
Bottom Line
The smartest move this festive season isn’t picking Amazon or Flipkart first and hoping your card works, it’s checking which bank is actually partnered with which platform, then shopping there with the card that matches. An SBI cardholder chasing Flipkart deals, or an Axis cardholder sticking to Amazon out of habit, is leaving real money on the table this year specifically because the partnerships have shifted.
