For that, we would use Python 3 and its libraries as it could be done with the Cloud, VPS, or a Raspberry Pi. We can use these libraries:
Python Requests to make requests and download HTML content (http://docs.python-requests.org/en/master/user/install/).

This code will do the given things:
Reads a listing about Total Wines and More URL from the file termed urls.txt (The file will get URLs for TWM products’ pages, which you care like Beer, Scotch, Wines, etc.)
Use a YAML selectorlib file to identify data on Total Wine pages which also gets saved in the file termed selectors.yml
Extract the desired Data
Save data in a CSV format file termed data.csv

In a urls.txt file, get”
Then, run the scraper having command:
If any site changes its assembly, e.g., CSS Selectors used for pricing in a file selectors.yaml termed price__1JvDDp_x might change daily.
A location’s selection for a “local” store could depend on variables and not geo-located IPs, and the website could ask to select a location. This is not held in the easier code.
The website could add original data points or change the present data.
The website could block the User-Agent
The website might block a design of using the script uses
Use a YAML selectorlib file to identify data on Total Wine pages which also gets saved in the file termed selectors.yml
The website might block IPs from different proxy providers
