Sticky Buy Box – Boost Sales with a Modern, Fixed Cart Bar

About the Extension

The Sticky Buy Box ensures that your "Add to Cart" area never leaves your customers' sight. As soon as your customers scroll down the product page and the standard buy box leaves the visible area, a sleek, modern bar appears at the top or bottom of the screen. This keeps the purchase just one click away – a real conversion booster, especially on mobile devices.

What the Plugin Offers You

• More conversions without more traffic
    Your visitors no longer need to scroll back up to buy. The Sticky Buy Box stays with them while they read texts, click through images, or check reviews – the buy button is always within reach.
• Clear focus on the purchase
    The bar shows exactly what motivates a purchase: product name, selected variant, price, and if applicable, strike-through/sale price, along with a clearly highlighted "Add to Cart" button. Unnecessary distractions are left out.
• Convenient variant selection directly in the bar
    For variant products, you can optionally display a compact variant trigger. This opens a configurable variant container where your customers can conveniently choose size, color, etc. – without interrupting the page flow.
• Always perfectly synced
    Changes to quantity and variants are synchronized bidirectionally between the original product box and the Sticky Buy Box. What you change at the top is immediately updated at the bottom – and vice versa.
• Perfect for Desktop, Tablet, and Smartphone
    You control which viewports the Sticky Buy Box should be active on. Special layout adjustments ensure that the title, variants, and price remain clearly legible even on small displays, keeping the buy button easy to click.

Design & Settings – Match the Box to Your Brand

• Position & Spacing
    Decide whether the bar is displayed at the top or bottom and set the distance from the edge of the screen – ideal for leaving space for cookie notices or other bars.
• Maximum Width & Corner Radius
    Set a maximum width (e.g., 1360px) so that the Sticky Buy Box doesn't run "edge to edge," but fits harmoniously into your layout. Use the adjustable border radius to match the look to your theme.
• Colors for Text, Buttons, Price & Sale Price
    Use the configuration to choose:    
  • Text color of the bar
  • Button colors including hover states
  • Custom colors for the regular price and sale price
  • A sale color that is automatically used as the background for the percentage savings badge
    If no custom settings are made, the plugin automatically falls back to your theme's default colors.
• Glassmorphism & Shadows for a Modern Look
    If desired, activate a subtle shadow and a semi-transparent, soft blurred background (backdrop blur). This makes the Sticky Buy Box look modern and high-quality while remaining discreetly in the background.
• Intelligently Integrated Scroll-to-Top Button
    To prevent your scroll-to-top button and the Sticky Buy Box from overlapping, you can configure additional spacing or hide the button on product detail pages when the Sticky Buy Box is active.
• Fine Control for Variant Products
    You can separately configure:    
  • Whether the Sticky Buy Box is displayed for variant products at all.
  • Whether the variant trigger and the variant container are visible for variant products.
    This allows you to use a compact layout for simple products while remaining flexible with complex variant items.

Who is the Sticky Buy Box for?

The Sticky Buy Box is ideal for you if:

• your product pages are long (many images, stories, technical details),
• you want more orders per visitor without intrusive pop-ups or aggressive banners,
• your shop relies heavily on mobile usage and you want to enable "thumb-friendly" purchases,
• you don't want to rebuild your theme, but are looking for a solution that adapts flexibly.

Thanks to the numerous design options, the Sticky Buy Box fits perfectly into both minimalist shops and visually strong brand presences.

In Summary

With the Sticky Buy Box, you make your purchase area always accessible without disrupting your design or annoying your customers. You increase the likelihood of turning interested visitors into actual buyers – with a modern, configurable bar that appears exactly when it's needed.
