With corporate, you get an additional 1-year accidental and liquid damage protection free of cost. The corporate store was selling the S24 Ultra Enterprise Edition* for around 74k with 1 year ADLD. When the Prime Day sale started, Amazon had matched the price, but as far as I remember, they did not give any bank discount on the S24U normal version; only Apay card benefits were available. If you use SBI cashback, it comes to the same price that people got from Amazon. And one thing to note is that you won't get any preactivated phone or any fraud due to the official store.
* The S24 Ultra Enterprise Edition has a 3-year warranty, only available at the corporate store for some specific models. Everything is same as the normal model; the only difference is the normal model will have a 1-year warranty, and that's all.
Now coming to your question you can wait for the sale. But keep in mind that the offers are dynamic in nature and can change anytime. What we anticipate may happen, or sometimes might not happen at all.
