With Lenovo laptops, it's easier to do the opposite - go to the psref.lenovo.com website, select only the model by MTM codes you are interested in the series and purposefully search for them in local stores using this code. With other manufacturers, everything is much more complicated, although the most advanced sites after Lenovo, of course, are the American HP and Dell (but they also have enough errors and incomplete information on the sites, like Lenovo). Relying on sellers' websites is not worth it - there is a lot of nonsense and gag in all countries, as my empirical experience has shown. Salespeople are generally incompetent people, despite the fact that according to the law(usually) they are considered as qualified persons based on their good faith attitude to the case (as is usually assumed in laws). Of course, this work is performed by their analytical department, but in 99% of cases its qualifications are insufficient compared to the current level of scientific and technical progress. Moreover, most of the staff are so stupid and lazy (not considering it their duty) that when I sometimes write the real state according to some models(not only laptops, but for many other products), with a clear indication of the sources of information - even large retail chains continue to keep incorrect and false descriptions for months, which clearly shows that they don't care and are counting on suckers, and prices are generally significantly inflated in terms of just for such an audience.
Only an expert who is completely immersed in the topic (who keeps hundreds, thousands of little things and details in head) can really evaluate any product and make a close(only), to the right, choice among the models offered on the market. But this requires unbiased and accurate tests from review to review, based on qualitatively formalized assessments of any product in a absolute (rather than relative) scale. Which requires a lot of hard work and the availability of a lot of equipment (updated in a timely manner, taking into account all possible advanced newest characteristics), and fully available, for the duration of the tests, to everyone who makes reviews.
And with all this in the world only growing problems. This is what marketers and TNCs use without any conscience.
