Sticky Add to Cart Button for Shopify
A sticky button pinned to the bottom of your product page opens your bundle deals in a popup, so the offer stays one tap away no matter how far shoppers scroll.

What is a sticky add-to-cart button?
A sticky add-to-cart button is a button pinned to the bottom of the product page that stays visible while the shopper scrolls through descriptions, reviews, and images. On long product pages, and especially on mobile, the buy area disappears within one swipe; the sticky button keeps the offer within reach the whole time.
In V Bundles, the sticky button (for example "View deals") opens your bundle widget in a popup, where the shopper picks the deal they want, like a quantity tier or a bundle, and adds it to the cart on the spot. The full offer travels with the customer instead of staying stranded at the top of the page.
What you can do with Sticky Add to Cart
Always within reach
The button stays pinned to the bottom of the page, so shoppers never have to scroll back up to buy.
Deals open in a popup
Tapping the button opens your bundle widget in a modal, where the shopper picks an offer and adds it straight to the cart.
Built for mobile
Most Shopify traffic is mobile, where product pages are longest and the buy area vanishes fastest.
Styled to match
Button text, colors, and layout are customizable so it looks native to your theme.
