The cart
Where: The cart icon, or the Cart chip in the top bar
Click the cart icon (its badge counts your distinct line items) or the Cart chip in the top bar.

The cart: line items, quantity steppers, coupon box and totals
Each line shows the product name, “SKU · unit price / unit”, a quantity stepper, the row total, and a trash icon to remove it. On the right: Subtotal, any Discount, and the Total.
Things worth knowing here:
- Re-check prices — prices in B2B move. This button re-resolves every line against current pricing and reports either “N price(s) updated to current pricing.” or “All prices are current.” Use it on carts you built days ago.
- Coupon code — type a code and press Apply. A valid coupon shows as a chip (“‹CODE› — ‹label›”) with an × to remove it; an invalid one says “That coupon code isn’t valid.”
- Free-shipping meter — if the store offers free shipping above a threshold, a progress bar tells you “Add ‹amount› more for free shipping” and celebrates “You’ve unlocked free shipping!” when you cross it.
- Show in — a display-currency selector. Pick another currency to see an indicative “≈ ‹currency› ‹amount›” conversion under the total. You are still billed in the store’s currency; this is for reference only.
When you’re ready, press Checkout.
If you filled a cart before signing in, pressing Checkout opens the “Ready to check out?” dialog: “Sign in to check out with your account pricing, or continue as a guest.” Sign in takes you to the sign-in page and brings you straight back. Continue as guest offers a minimal “Continue as guest” account form (name, company, email, password) — after which you must still click the emailed verification link, and your cart comes with you.
If an add-to-cart fails, the message tells you why: “This product has options — open its page to configure it before adding.” (configurable product), “Already in your cart as a configured item — edit or remove it from the cart.”, or “No price available — request a quote for this product.” (price on request).
