Michaels Web Coupon Stacker

WHAT IT DOES

Michaels Web Coupon Stacker reads available coupons from the Michaels homepage and coupon page and displays a floating coupon stack badge showing the count of available coupons. The badge shows the total number of coupons, the best available discount (highlighted with a star badge), and a list of coupon descriptions. Each coupon is tracked with its description, discount percentage, and expiration date. The extension tracks coupon viewing history per session, so you can see which coupons you've already seen. A notification system alerts you when new coupons are available, with a one-hour cooldown to prevent spam. The panel settings let you control overlay visibility, refresh coupons, toggle expired coupons visibility, and adjust notification preferences.

WHERE IT RUNS

This extension works on all Michaels pages at michaels.com and its subdomains, specifically on the homepage, coupon page, and any page displaying promotional offers. It runs on the main feed, the coupon listing page, and any page showing coupon information. The extension operates entirely within your browser and does not access Michaels' servers directly—it reads only what is visible on the page you are viewing. It works alongside the free BotGentz extension, which provides the necessary scripting environment.

HOW TO USE

Install the extension, then navigate to michaels.com and browse for coupons. The extension automatically creates a floating coupon stack badge on the page showing the count of available coupons. Click the extension's icon in your browser toolbar to open the settings panel. Use the "Show Overlay" / "Hide Overlay" button to toggle the badge visibility. The "Refresh" button manually updates the badge with the latest coupon information. The "Show expired coupons" toggle controls whether expired coupons appear in the digest. The "Show notifications" toggle controls desktop notifications for new coupons. The opacity dropdown adjusts overlay transparency (70%, 82%, 92%, or 100%). Drag the badge by clicking and holding anywhere inside it. Resize it by dragging the bottom-right corner. Close the badge with the × button.

COUPON EXTRACTION WITH DISCOUNT PRIORITIZATION AND EXPIRY TRACKING

Unlike simple coupon counters, this extension uses a multi-selector extraction engine to find coupon items from Michaels' varying page structures. It searches for coupons using multiple selector patterns (.coupon-item, .offer-item, .promo-card) and falls back to text parsing. For each coupon, it extracts the description, discount percentage, and expiration date using pattern matching and date parsing. The discount extraction uses regex to find percentage values in both dedicated discount elements and text descriptions. The best coupon is determined by finding the highest discount percentage among active coupons. Expiration dates are parsed using date extraction regex that handles multiple formats. Coupon viewing history is tracked per session using a session ID, storing viewed coupon IDs as an array to avoid showing the same coupons repeatedly. The notification system triggers when new coupons are detected, with a one-hour cooldown.

THE PANEL

The panel supports drag-to-move anywhere on the page. It remembers its position per site, so it stays where you placed it on michaels.com. Click the panel header to collapse it down to just the minimized bubble, or click the expand handle to show the full panel. The panel can be resized by dragging the bottom-right corner. Press the Escape key to close the expanded panel and return to the minimized state. All panel settings, including position, size, collapsed state, opacity, expired coupons visibility, notification preference, and coupon history, are saved per site and persist across browsing sessions.

PLEASE NOTE

This extension requires the free BotGentz extension to be installed and active, as it provides the underlying DOM injection and script execution environment. Michaels' website changes periodically, and coupon element structures, class names, and page layouts may be updated. When that happens, the extension may stop detecting coupons until an update is released. The extension stores your overlay position, size, opacity, visibility, expired coupons preference, notification preference, and session-based viewed coupon IDs locally in your browser's storage using GM_setValue. Viewed coupons are stored as an array of coupon IDs per session ID. The coupon count is based on coupons visible on the page—the extension does not access Michaels' internal coupon data. Always verify with Michaels directly for the most current coupon information. No data is ever sent to any server, and no personal information is collected. You can clear all stored settings at any time by clearing your browser data for michaels.com.
