BestBuy
Complete guide on our BestBuy module
Our Best Buy module supports both account based and guest checkout, with dedicated modes for shipping, pickup, account generation, monitoring and invite flows. Best Buy is heavily queue based, but Stellar helps manage sessions, IMAP verification, and monitor to checkout workflows so you can focus on timing and product selection. This module is ideal for high demand products, electronics, GPUs, consoles, PCs and accessories that release in waves, use queues or restock at random.

Quick Start (Recommended Setup)
Add your Best Buy account under Identities → Best Buy.
Enable IMAP for your email so Stellar can auto pull Best Buy verification codes.
Create profiles with matching email = Best Buy account email.
For each SKU, run:
1 Monitor task per SKU (Monitor and/or Monitor-zip modes)
Strictly 1 Shipping task OR 1 Pickup task per account per SKU
Use ISPs for monitoring and residentials for checkout.
Before big drops, reset passwords the day before using unique proxies per account.
Use Watch Task for restocks so Monitor tasks do the heavy lifting.
Preliminary Checklist
Before setting up tasks on BestBuy, make sure you have everything below prepared:
Create and save your checkout profiles under the Profiles tab in Stellar. These contain your billing, shipping and payment info.
ISP proxies – Recommended for some of your tasks
Residential proxies – Recommended for majority of your tasks
Save both proxy groups under the Proxies tab in Stellar.
If you're looking for proxies, check out Stella Proxies for high quality ISP and Residential proxies
Required for account based checkout.
Each session stores login, proxies, and (optionally) tax exempt details.
Lets Stellar automatically pull Best Buy verification codes from your email.
Greatly reduces friction during resets/logins.
Resetting your Best Buy account passwords the day before a drop can help reduce queue loops and weird login behavior.
Before big drops, run a test task on a random in stock product to confirm your profile, account, proxies and delays are functioning correctly.
Sessions & Login
Follow the steps below to start adding your BestBuy accounts to Stellar. If you have a lot of accounts and want to mass import them quickly go here
1. Go to Identities tab and select BestBuy
2. Click on Add Session and name your Session
3. Fill fields:
Email – Best Buy account email
Password – Best Buy account password
Login Proxy – ISP proxy recommended (used for queues + login)
Tax Exempt Number – if using business account with tax exemption
4. Click Save and your Session should say Ready To Login. Your task will log into your account upon starting. The BestBuy account email has to exactly match (case sensitive) the email you have in your profile. You can run a test task on an in stock item to ensure everything is setup correctly. Your sessions will then change to Ready once your task once was able to log into your Best Buy account successfully

Sessions are created automatically for each generated account.
Shipping Mode
Used when you want items shipped to your address.
Make sure the product supports shipping (some SKUs are pickup-only).
Your cook group can confirm fulfillment type.
Pickup Mode
Used when you want in store pickup.
Works with Pickup Radius and/or Store IDs depending on monitor mode.
Only use for products that offer pickup.

Pings checkout tasks with matching SKUs when stock appears.

Useful for region-based availability.
Monitor-stores Mode
Monitors products based on specific Store IDs.
Great for targeting specific physical locations.
Profile
Choose a profile that has the same email as the Best Buy session you want to use.
If Guest Mode is enabled, it uses profile info without the account.
For account checkouts, the email must match exactly (case sensitive).
Proxies
ISPs → best for monitoring/login
Residentials → best for checkout tasks
Combine as needed based on your setup.
If you're looking for proxies, check out Stella Proxies for high quality ISP and Residential proxies
SKUs
A SKU is a unique ID for a specific Best Buy item.
You can only enter one SKU per task.
Example link:
SKU = 6084400
Store IDs (Monitor-stores Mode)
Used when monitoring for store-specific availability.
You can find Store IDs at:
https://stores.bestbuy.com/index.htmlClick a state → click a store → note the store ID.
Delays
General recommended delay: ~4500 ms
Adjust based on proxies and site behavior; always test before big drops.
Quantity (QTY)
Check with your cookgroup for recommended QTY per product.
Stellar does not auto adjust QTY if you exceed site limits.
Pickup Radius (Pickup Fulfillment Only)
Used with Pickup Mode.
Represents the max distance (miles) from your profile’s shipping zip code.
Max: 250
Blank = default 25 miles
Only enter whole numbers (e.g., 50, 75).
Leave this blank when running Shipping fulfillment.
IMAP Session
Choose which IMAP session to use for this task.
Needed for account verification, 2FA emails, password resets.
Guest Mode
Check this box for guest checkout (no Best Buy account).
Uses profile info only.
Uncheck to use an account based checkout via sessions.
Watch Task
Highly recommended for restocks.
When enabled:
Checkout task (Shipping or Pickup) waits for Monitor task
Monitor task (with same SKU) detects restock
Monitor task pings the checkout task
Checkout task adds to cart and completes checkout
Behavior:
When started, checkout task shows: “Waiting for Monitor Ping.”
Monitor finds stock → checkout begins immediately
If you leave Watch Task unchecked:
Checkout task monitors and checks out on its own
Higher load and more requests from a single task
Skip Prelogin
Enabled → Bot skips pre-login and waits directly for Monitor Ping.
Useful when there is a known queue; avoids pre-login slowing things down.
Disabled → Bot logs into account when starting the task.
Better for using stored payment methods or when no heavy queue is expected.
If a queue is active, enabling Skip Prelogin is recommended.
Rakuten & TopCashback
Use Rakuten → check after following Rakuten guide to earn cashback.
Use TopCashback → check after following TopCashback guide to earn cashback.
Delivery Options
