Shipping Estimator on Product Page

No. The estimate uses your existing shipping methods and rates through the CS-Cart shipping calculation, the same one checkout uses.

Yes. Realtime carriers are asked for a live rate in the background, so the product page is never slower. Results are cached for a few minutes (setting). If a carrier does not answer within 12 seconds, the box says that shipping costs are calculated at checkout. You can also leave realtime carriers out of the estimate.

Usually because the cart contains other products: weight or order total based rates and free shipping thresholds then change. Switch on Include the customer's cart in the estimate to calculate with the cart. A guest without a location sees the rates for your store's default location until they enter theirs.

From your dispatch days, cut-off time, holidays and handling time, plus the transit days of each shipping method (or its delivery time text such as "3-5 days"). With Kavio Delivery Date & Time Slots installed, its calendars are used. See Delivery dates.

Yes. Products have a Handling time (days) field on their admin page. On Multi-Vendor, vendors set their own handling time and cut-off time in their profile (you can switch this off).

Yes, from version 1.0.1. When Kavio Stock Statuses & Lead Times shows a status with a lead time for the product (for example "Ships in 3–5 days"), the estimate counts that lead time as the least handling time of the product, so the delivery date starts after the dispatch date the status promises. A longer handling time of the product, vendor or store still wins. Without that add-on, or for statuses without a lead time, nothing changes.

With the Change link in the box: country, state, postcode and city. The location is remembered for the next product pages. Signed-in customers see their profile address first.

Yes. The cached product page contains only a placeholder that is the same for every visitor; each visitor's estimate is loaded separately and never stored in the page cache.

No. The estimate is calculated on a temporary copy that is never saved. Checkout charges exactly what it charged before.

Yes. Choose Below the product form, or Block only and place the Delivery estimate block in Design → Layouts. The colours follow your theme and can be changed with a few CSS custom properties (see Developer notes).

Without a valid license (no key after the 14-day start period, an invalid or revoked key, a domain the license does not cover, or no successful check for 14 days), the delivery estimate on product pages and its block are hidden. Checkout, shipping rates and orders are not affected. Once the license is valid again, everything is back.

Open Add-ons → Manage add-ons → Shipping Estimator on Product Page: the License card at the top says what is wrong. Fix it on the License tab and click Check now. See License.

Yes. Subdomains of your licensed domain and local development hosts (localhost, private IP addresses, .local, .test) are covered by the same license.

Nothing changes for 14 days: the add-on keeps working and retries every hour. Only if no check succeeds for 14 days is it switched off until the next successful check.

No. The check runs only in the admin panel or from cron, at most once a day, never while customers browse or check out.
