What these cost before the sale

• Low, usual and high are what the product cost on that platform between 18 August 2026 and 17 September 2026. Usual is the middle value.
• Latest is the most recent in-stock price we recorded on the same platform, with the date it was recorded shown under it. Amazon is compared with Amazon and Flipkart with Flipkart, never one shop's sale with another shop's normal price.
• A price marked new low is cheaper than anything we recorded on that platform between 18 August 2026 and 17 September 2026.
• Week before is the usual price on the same platform between 17 September 2026 and 6 October 2026, from the second record. It is marked rose or fell when it is 10% or more above or below the first record's usual price.

3 series were withdrawn after the record was frozen. Each one contained a listing we later found to be a different product, so its figures could not stand:

• Philips Bhd356 on Amazon. Included a listing selling the BHD356 hair dryer and a BHH880 straightening brush together, which raised the recorded high to Rs 5,645.
• Philips Bhd356 on Flipkart. Included a listing for the Philips BHH880 straightening brush, a different product.
• Philips Bt3303 on Amazon. The only Amazon listing was a Philips BT3325, a different model.

The frozen record itself is unchanged. The withdrawn series are listed in a separate corrections file, so anyone holding the original can see exactly what changed.

• Products are matched across platforms by manufacturer model code, not by title, so each row is the same physical product.
• Products are not all checked every day. Each product and platform was recorded on a median of 7 separate days within the 30, so low, usual and high describe those observations, not every day in the window.
• Each series takes the cheapest observation on that platform per day. Observations far from the series' own usual price are dropped as likely wrong listings, and a series that needed too many dropped is left out entirely.
• When the latest price is more than double the usual price, or less than 30% of it, we show it without a comparison. That is usually a wrong listing rather than a real change.
• This is a record, not a verdict. A higher price today is not wrongdoing, and a lower one is not proof of a good deal. It shows what we observed and when.
