Price list/price aggregator - which one is more convenient (from the side of buyers)?

Question

Conversion

Hello.
When you know exactly the right model of the purchased product and want to buy a quality product at the lowest price and with a manufacturer's warranty, then...
1. What price aggregator (or maybe some other interesting service) do you use?
2. Why is this service convenient / inconvenient? (and ease of use on a 10-point scale)
3. What functionality would you like to add / what is missing?
4. Do you trust the information from the administration of the service (in terms of "all stores are checked by our quality service", "the rating is set according to the formula", etc.) and why?
5. Do you trust reviews about the store / products located on this service?
6. How do you decide for yourself that this store is reliable (and that "this store is worth taking")?
7. What is the reason for your choice of this service?
8. What is the best and worst service in your opinion.
In advance everyone, Thank you very much for your replies.

Answer 1

1. I just use an online store.
2. I can sometimes use hotline or price.ua as an aggregator, but rarely - I still have to double-check the price, and if there is suddenly a low price, then 99% that this is some obscure company forgot to update its price, so sorting in hotline and price .ua has no real meaning. In addition, it does not take into account the cost of delivery, possible promotions, etc.
If the item is popular - in all large stores it is about the same price, so I check a maximum of 2-3 (for Kiev, for example, a socket, fotos)
3. links to the manufacturer's website, carefully check the descriptions so that there is no point 4
4. For expensive things, I'm not too lazy to read the specification on the manufacturer's website in order to exclude typos.
5. large stores are full of users. There are over 100 reviews on popular products, among them real reviews, including negative ones, are quite clearly visible. But at least reviews with a technical description of what exactly was bad are useful.
6. Experience of previous purchases. The probability of acquiring an expensive item in a previously unexplored store tends to zero.
7. The choice of goods.
8. I do not get along on unknown sites. Why climb the bad ones if there is a way that already works.
