Everything you need

Built for the way
people actually shop

Most people shop across 5–10 different stores for a single haul. Big Bag was built for exactly that.

🛍
Save from anywhere

A floating "Save to Big Bag" button appears automatically on any product page. One click captures the title, price, image, selected variant, and link.

🏷
Smart grouping

View your bag grouped by store, product category (auto-detected), price range, or your own priority tags. Switch views instantly.

💰
Running total

See your estimated grand total across all stores and currencies, updated in real time. Know exactly what you're about to spend before you commit.

Buy All

One button opens each product page, automatically adds to cart, navigates to checkout, and autofills your saved shipping details.

Checkout autofill

Save your name, address, and payment details once. Big Bag fills checkout forms automatically on any store — no retyping, ever.

🌙
Light & dark mode

A sleek dark mode with gold accents, and a crisp light mode with fuchsia accents. Both designed to feel fashion-forward, not generic.
