Is it any opportunity to download my competitors' prices from the site?

[Kosta_Bankovski]

I need to compare prices from another site with mine but it's too long to do it manually, is it any way how to download them?

Depends on what website you're talking about and it's architecture. But it's doable.

You can download prices (or anything else) by parsing the element where it's encased from every page.
It can be a CSS selector, XPath or plain HTML.

Get a crawler with custom settings. Netpeak Spider (I work at Netpeak Software, this is a tool we developed) or Screaming Frog (I guess frog can also do this).

You'll have to get your crawling settings right.
Here's a brief rundown on the process:

• Find an element you want to download (price on the product page)
• Right click on it and click inspect.
• A console will open and this element will be highlighted.
• Depending on how this element is built you'll need to copy its XPath, CSS, or entire HTML. Trial and error if you don't know much about web development.
• Then use the crawler to parse all data from elements similar to the one you've inspected

You'll probably have to contact our support to help you with settings the first time.

If you have no budget limits or don't feel like doing it on your own there are companies which specify in this. Like Competera, Countly and etc.
