How we reached this
Last year's cuts are the ones named outlets reported during Black Friday week 2025, against the regular price they quoted. The forecast is our reading of each model's age, its successors and last year's cuts. We never show prices. Where no outlet reported a cut in this country, we show the same model's cut reported in another country, marked with that country.
We haven't tested these products ourselves. Our picks weigh independent expert reviews against each maker's published specs and the prices we checked. Opinions are ours; facts link to where they come from. How we choose.
