safeway-coupons¶

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

safeway-coupons is a tool 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 Google Chrome. Authentication may fail based on your IP's reputation, either by presenting an interactive challenge or denying sign in attempts altogether.

safeway-coupons currently does not have support for prompting the user to solve interactive challenges.

Safeway's sign in page may also require an email verification code. Support for email verification codes is being evaluated. To reduce the frequency of MFA challenges, a persistent Google Chrome profile directory is created for each account and reused for logins with the same account. These are stored within the User state directory (see user_state_dir).

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

Installation and usage¶

Prerequisites¶

Google Chrome (for authentication performed via patchright).
Optional: sendmail (for email support)

Installation¶

Installation with uv or pipx is recommended:

uv tool install safeway-coupons

pipx install safeway-coupons

Installation with pip is also available:

pip install safeway-coupons

Usage¶

For best results, run this program once a day or so with a cron daemon.

For full usage options, run

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:

; optional
email_sender = sender@example.com

; required
[safeway.account@example.com]
; required
password = 12345
; optional
notify = your.email@example.com

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

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

Installation and usage with Docker Compose¶

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 compose.yaml with configuration via environment variables:

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: your.safeway.account.email@example.com
      SAFEWAY_ACCOUNT_PASSWORD: very_secret
      SAFEWAY_ACCOUNT_MAIL_FROM: your.email@example.com
      SAFEWAY_ACCOUNT_MAIL_TO: your.email@example.com
      # EXTRA_ARGS: --debug  # Optional
    restart: unless-stopped
    volumes:
      - state:/state:rw

volumes:
  state:

Example compose.yaml with configuration via accounts file:

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
      - state:/state:rw

volumes:
  state:

Start the container by running:

docker compose up -d

Debugging information can be viewed in the container log:

docker compose logs -f

Development¶

Invocation with `docker compose`¶

safeway-coupons can be executed within a Docker container using compose.dev.yaml.

To use, first create an accounts file in the same directory with your safeway-coupons accounts configuration. Then, execute safeway-coupons within a container using docker compose:

docker compose -f compose.dev.yaml up --build

The container will run safeway-coupons once, attempt to clip one coupon, and then stop.

To change the safeway-coupons arguments, modify the command value in compose.dev.yaml.

When finished with development tasks, the docker compose state can be cleaned up with:

docker compose -f compose.dev.yaml down
