# Cart Prices and Missing Gifts

A bundle's price can change when a customer changes the quantity or removes a product. Start by checking the items in the cart.

## The Discount Is Different

Check the selected variants, quantities and discount settings. Some variants may have different prices.

For **Buy X Get Y**, check **Customer buys (X)** and **Customer gets (Y)** separately. The two groups can have different discounts.

For a mixed-product bundle, check the discount on each product.

## A Gift or Upsell Is Missing

Check that the customer has selected a tier that includes the item. Then check that the gift or upsell product is available on the Online Store and has stock.

A checkbox upsell is optional. The customer must select its checkbox before adding the offer to the cart.

## A Gift Has a Price

Check whether the cart still meets the offer's quantity requirement. A gift can stay in the cart at its regular price after the customer removes a qualifying item or lowers the quantity.

For a half-price or other discounted bonus, check its **Discount** setting. A bonus item is only free when its discount is set to **Free**.

## Only Some Items Were Added

If a stock warning appears, reload the cart before adding the offer again. Check which items are already there to avoid adding them twice.

## The Checkout Total Is Higher

Compare the product subtotal first. Shipping and tax can change the final total. Also check any discount code used at checkout.

If the product subtotal is still wrong, share the product link, selected variants, quantities and screenshots of the offer and cart with support.
