Promo Cart Progress Bar for Magento 2

From the Promotions core (commercegears/module-promo-core): the Free Shipping method's "Minimum Order Amount", cart price rules without a coupon that give free shipping and have a top-level "Subtotal equals or greater than" condition, CommerceGears Free Gift rules and CommerceGears Tiered Discounts tiers when those modules are installed and switched on, and the milestones you add yourself under CommerceGears > Promotions > Cart Progress Bar: Milestones.

Yes, the same way Magento does. Magento checks a free shipping rule's "Subtotal" condition on the whole basket; the "Apply to" conditions only decide which items the reward covers. So the bar counts the whole basket and shows free shipping as unlocked exactly when Magento gives it.

Only two kinds of milestone count some items: Tiered Discounts tiers whose campaign counts only some items, and your own milestones with Items That Count (categories, SKUs). They say "Only qualifying items count" on the cart page.

No. Your own milestones only show a reward on the bar. Set up the reward itself as a cart price rule (or in the module that gives it) with the same amount and the same cart amount (subtotal excl. or incl. tax, before or after discounts).

They share one marker and one message, for example "Spend £20.00 more for a free gift and 10% off". The sort order in the Milestone Sources table (and on your own milestones) decides which reward is named first.

Yes. Stores > Configuration > CommerceGears > Cart Progress Bar > Milestone Sources: set "Show" to No for that source. "Other Modules" decides for sources that are not listed.

Both can show. If you prefer only the progress bar, switch off Free Gift's Spend More Notice and the cart and mini cart messages of Tiered Discounts. Their thresholds stay on the progress bar.

From the sources you pick (cross-sells, related and up-sell products of the cart items, a chosen category, bestsellers), in that order, keeping only products that are enabled, visible in the catalogue, in stock, not in the cart yet and priced between the amount still needed and that amount plus a percentage (default 30%). Simple and virtual products without required options get an "Add" button; others link to their product page.

Pages only contain an empty placeholder, so they stay in the full page cache. The bar's data is part of Magento's customer data, which loads after cart changes and logins. Upsell candidates are cached per price band, store, customer group and currency (default 30 minutes).

Yes. Milestone amounts are in the base currency and shown in the cart's currency. Each milestone is compared with the cart amount its source declares, for example the Free Shipping method's setting "Include Tax to Amount".

Item-count hints. Some rewards count items instead of money, for example a Bundle Builder pack ("Add 1 more item to complete your pack") or a quantity tier ("Add 2 more items for 10% off"). They show under the bar in the mini cart and cart. Switch them off or set how many show under Where to Show the Bar, or hide one source in Milestone Sources.

Only when the product's own price would reach the next milestone, for example "Add this item and get free shipping". Discounts that would apply to the new item are not taken into account.

Sessions that saw the bar with items in the cart, upsell clicks and adds, carts that reached each milestone (once per cart), and orders whose cart had reached each milestone, with revenue and average order value compared with all orders that were not cancelled.

Yes, with the close button. It stays hidden for the rest of the browser session.

The bar uses role="progressbar" with the current value and the message as text, the message is announced politely when it changes, buttons work with the keyboard and the animation is off when the visitor prefers reduced motion.
