safeway-coupons 0.2.6

Automatic coupon clipper for Safeway's online "Safeway for U" coupons

Automatic Safeway coupon clipper

safeway-coupons is a script that will log in to an account on safeway.com, and attempt to select all of the "Safeway for U" electronic coupons on the site so they don't have to each be clicked manually.

Design notes

Safeway's sign in page is protected by a web application firewall (WAF). safeway-coupons performs authentication using a headless instance of Google Chrome. Authentication may fail based on your IP's reputation, either by presenting a CAPTCHA or denying sign in attempts altogether. safeway-coupons currently does not have support for prompting the user to solve CAPTCHAs.

Once a signed in session is established, coupon clipping is performed using HTTP requests via requests.

Installation and usage with Docker

A Docker container is provided which runs safeway-coupons with cron. The cron schedule and your Safeway account details may be configured using environment variables, or with an accounts file.

Example docker-compose.yaml with configuration via environment variables:

version: "3.7"

services:
  safeway-coupons:
    image: ghcr.io/smkent/safeway-coupons:latest
    environment:
      CRON_SCHEDULE: "0 2 * * *"  # Run at 2:00 AM UTC each day
      # TZ: Antarctica/McMurdo  # Optional time zone to use instead of UTC
      SMTPHOST: your.smtp.host
      SAFEWAY_ACCOUNT_USERNAME: [e-mail]
      SAFEWAY_ACCOUNT_PASSWORD: very_secret
      SAFEWAY_ACCOUNT_MAIL_FROM: [e-mail]
      SAFEWAY_ACCOUNT_MAIL_TO: [e-mail]
      # EXTRA_ARGS: --debug  # Optional
    restart: unless-stopped

Example docker-compose.yaml with configuration via accounts file:

version: "3.7"

services:
  safeway-coupons:
    image: ghcr.io/smkent/safeway-coupons:latest
    environment:
      CRON_SCHEDULE: "0 2 * * *"  # Run at 2:00 AM UTC each day
      # TZ: Antarctica/McMurdo  # Optional time zone to use instead of UTC
      SMTPHOST: your.smtp.host
      SAFEWAY_ACCOUNTS_FILE: /accounts_file
      # EXTRA_ARGS: --debug  # Optional
    restart: unless-stopped
    volumes:
      - path/to/safeway_accounts_file:/accounts_file:ro

Start the container by running:

docker-compose up -d

Debugging information can be viewed in the container log:

docker-compose logs -f

safeway-coupons --help

Configuration

safeway-coupons can clip coupons for one or more Safeway accounts in a single run, depending on the configuration method used.

If a sender email address is configured, a summary email will be sent for each Safeway account via sendmail. The email recipient defaults to the Safeway account email address, but can be overridden for each account.

Accounts are searched via the following methods in the listed order. Only one account configuration method may be used at a time.

With environment variables

A single Safeway account can be configured with environment variables:

• SAFEWAY_ACCOUNT_USERNAME: Account email address (required)
• SAFEWAY_ACCOUNT_PASSWORD: Account password (required)
• SAFEWAY_ACCOUNT_MAIL_FROM: Sender address for email summary
• SAFEWAY_ACCOUNT_MAIL_TO: Recipient address for email summary

With config file

Multiple Safeway accounts can be provided in an ini-style config file, with a section for each account. For example:

email_sender = [e-mail]   ; optional

[[e-mail]]       ; required
password = 12345                    ; required
notify = [e-mail]     ; optional

Provide the path to your config file using the -c or --accounts-config option:

safeway-coupons -c path/to/config/file
