Features:

Secure card information storage and management
Support for multiple payment gateways
Recurring payment and subscription management
Robust validation and error handling
Highly customizable and flexible architecture

From the package's documentation, here's an example of retrieving a cart for a given user and adding an item to the cart:

$cart = Cart::query()->firstOrCreate(['user_id' => $user->id]);
$cartItem = new CartItem([
    'itemable_id' => $itemable->id,
    'itemable_type' => $itemable::class,
    'quantity' => 1,
]);
 
$cart->items()->save($cartItem);
 
// Or create and store
Cart::query()->firstOrCreateWithStoreItems(
    item: $product,
    quantity: 1,
    userId: $user->id
);
