About Cart item limits
You can add up to 30 items per cart. After that, you'll need to checkout before you can proceed to create a new cart with additional items for that shop.
Why is there a cart item limit?
From our experiencing processing hundreds of thousand of orders, we've determined that it's better for everyone to limit carts to no more than 30 items. Having too many items can really slow things down, especially when some items are out-of-stock, or other concerns and adjustments which require back-and-forth communication with you, our dear customer.
