Price consistency to checkout: what Merchant Center requires
The price a shopper sees on the product page has to be the price in the cart and at checkout; Google lets it fall with a promotion, never rise. Walk one order through and write down every number. Surprises at the last step are the ones people remember.
Why this matters
Google's “Checkout requirements and best practices” page is direct: “The price of your product must be consistent throughout the checkout process, not just between the product data source and your product page. The price must not increase at checkout, but it can be reduced after the product is added to the cart if a promotion is applied.” It opens with the shopper's view: “People expect to pay the advertised price for products.”
The product page has its own rules on the “Price [price]” page. “Display variants and their prices in a straightforward way on your landing page”, so the price moves when the shopper picks a dearer size. A discounted price counts only if “The discount or coupon prices are freely available to every user” and “The price after applying the discount or coupon is displayed clearly on the landing page.” A page price that assumes a code the shopper has not been given is not the price they pay.
Everything outside the item price has a place of its own. Shipping goes in your shipping settings, not the price, and fees you add at checkout belong in the shipping cost you submit, as hidden checkout fees explains. Tax depends on the country: included in the price where Google's price rules ask for VAT, left out in the US and Canada; see tax at checkout. Get those right and the item line never needs to move between the product page and payment.
Verify a price correction using the same variant, quantity, destination and currency at each step. Record the item price separately from shipping and tax, then repeat the path after publishing the change.

Typical evidence
The price that climbs after the click
When a product page says one thing and the cart says more, shoppers need a clear explanation before they buy. Test that journey directly; StoreVerifier can capture public evidence but cannot determine enforcement or an account result.

What it looks like once it is right
Illustrative fix: correct the product template so the selected size shows £88 before adding it. Repeat the same size and quantity through the basket and checkout, then compare the submitted variant price manually. The captured item prices agree; no suspension result is implied.

Three places the number quietly climbs
A price jump is never a mystery once you know where to look. It’s almost always one of three culprits adding to the figure between the listing and the cart — and each one is fixable the moment you’ve named it.

Questions merchants ask
Can the price in the cart be lower than on the product page?
Yes. Google's checkout requirements say the price must not increase at checkout, but it can be reduced after the product is added to the cart if a promotion is applied, for example a discount code.
Can my product page show a price that needs a coupon?
Only if the coupon is freely available to every user and the discounted price is displayed clearly on the product page, as Google's “Price [price]” page requires. Otherwise show the full price and let the code reduce it in the cart.
What about variants with different prices?
Each variant’s price has to be shown in a straightforward way on the product page, and your product data should carry each variant as its own item with its own price. See variant pricing.
