Costcoholic – See What Costco Is Really Costing You
Based on the popular posts from Reddit users ViKoToMo (https://www.reddit.com/r/Costco/comments/1p4w903/costco_damage_to_wallet_fork/?sort=new) and ikeee (https://www.reddit.com/r/Costco/comments/1p47dzr/the_damage_costco_has_caused_my_wallet_over_3/)

Costcoholic turns your Costco account history into a clean, visual dashboard so you can finally see where your warehouse, gas, and online spending is going.

Once installed, Costcoholic adds a “View Spending Summary” button on Costco’s Order Status page. Click it and the extension:

Securely pulls your Costco receipts (warehouse, gas, and online orders) using the same APIs the site uses.
Builds an interactive dashboard with:
Total spend (net of returns) and trips over time
Average spend per trip
Top warehouses you visit most
Detailed stats for gas (trips, gallons, cost, avg price/gal)
Item-level insights: most purchased items, most total spent items, biggest price increases, most expensive items
Rotisserie chicken tracking (because of course)
Lets you export a “Wrapped-style” PNG summary that’s optimized for sharing on social (Reddit, Instagram, etc.).

Why install it?
Instant visibility into your Costco habits – See how much you actually spend, when, and on what, instead of guessing from scattered emails and paper receipts.
Local and privacy-conscious – All processing happens in your browser. Data is stored in Chrome’s local storage and is never sent to any server controlled by this extension.
Spot trends and price creep – Identify which items are quietly getting more expensive and which categories dominate your wallet.
Gas and returns included – Separate out gas trips, track cost per gallon, and see how much you’ve clawed back in returns.
Shareable summaries – Generate a polished “Costcoholic Wrapped” image to compare spending with friends or post online.
If you regularly shop at Costco and have ever wondered “what’s the damage this year?”, Costcoholic gives you the answer in one click.
