Best Buy Price Tracker: BestBuy Monitoring Tool

How do you get a Best Buy price stalking artifact? Teach yourself how to build your own tool with a proxy IP

A lot of old timers have been asking lately how to keep an eye on the price changes of items on BestBuy in real time. For example, if you want to grab a discounted graphics card or restock a game console, it's simply unrealistic to rely on manual refreshing. Here is a trick for the guys, with Python script + proxy IP to build their own monitoring tools, the point is not to spend a lot of money can also be 24 hours of automatic stalking.

Why do you have to use a proxy IP?

The big platforms like BestBuy haveanti-crawler mechanismThe same IP is frequently accessed, and it is certain to be blacked out. Last year, a buddy even brushed the page 200 times, and the account was blocked. Using a proxy IP is, frankly speakingChange your armor and get back to work., every time a request is made for a new IP, the platform doesn't recognize that it's the same user operating.

import requests
from ipipgo import get_proxy Here we use the ipipgo SDK.

def check_price(url): proxy = get_proxy()
    proxy = get_proxy() Automatically get available proxies.
    headers = {'User-Agent': 'Mozilla/5.0'}
    try.
        response = requests.get(url, proxies={"http": proxy, "https": proxy}, headers=headers)
         Here's the price logic to parse...
        return price
    except Exception as e.
        print(f "Request failed, retry with another IP: {e}")

This is done in three steps

Step 1: Register for a ipipgo account
They have a free trial package for newcomers, and you can get 5,000 IP calls for 3 days with a WeChat scan. Pay attention to the selectionResidential Dynamic IPpackages, this IP segment is closest to real users.

Step 2: Configure a rotation strategy
It is recommended to set the IP to change every 5 requests, don't change it too often instead of being suspicious. Use their API to get the latest available IP directly:

 Example of getting proxy IP
API_URL = "https://api.ipipgo.com/get?key=你的密钥&type=json"
response = requests.get(API_URL)
proxy_ip = f"{response.json()['ip']}:{response.json()['port']}"

Step 3: Exception handling should be in place
In these cases you must change your IP immediately:
1. Three consecutive request time-outs
2. Return status code not 200
3. CAPTCHA appears on the page
It is recommended to increase the frequency of monitoring from 2-5am, the time when the platform is most loosely defended.

Frequently Asked Questions

Q: Is it okay to use a free proxy?
A: Never! Nine out of ten free IPs are pits, either slow as a tortoise, or have long been flagged by the platform. Previously tested a treasure to buy a cheap proxy, the success rate is less than 30%, and finally had to use ipipgo professional line to save the day.

Q: What is the appropriate monitoring frequency?
A: Hot items are checked every 15 minutes and cold items every 2 hours. If you find a sudden fluctuation in inventory, you can temporarily raise it to a 5-minute check.

Q: What should I do if ipipgo's IP is not working?
A: Their background will automatically eliminate failed nodes, and the IP pool will be updated within 10 seconds of the actual test. In case you really encounter problems, look for customer service to report the error code, the response speed is at least twice as fast as the counterparts.

A Guide to Avoiding the Pit (Blood and Tears)

1. Don't write a dead IP address in the code, always use the dynamic acquisition method
2. User-Agent remembers to mimic a real browser and recommends this combination:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36
3. After monitoring the price changes, it is best to add a text message alert function (using the API of the Aliyun or Tencent cloud on the line)

Lastly, I'll tell you a true story: last month, I used this method to keep an eye on the RTX4090, and I managed to catch BestBuy releasing a batch of original-price cards, which were over 4,000 dollars cheaper than the scalper's price. The tool is set up and put on the automatic run on the line, than every day squatting web page to save a lot of worry. The key is to choose the right proxy service provider, ipipgo used for half a year has not overturned the car, the need for the old iron can go to the official website to take a look at the package.
