About Grand Total

Build your shopping list as you shop — see what it costs delivered, not per item. Grand Total sits quietly on a shop's product page. Find something you want, add it to your list with one click, and keep browsing. Once your list has more than one item, a sidebar shows what the whole order would cost delivered — at this shop, or split across others — compared with just finishing checkout where you're standing. Why delivered total, not price per item? Shipping is charged per order, not per item, and free-shipping thresholds aren't linear. A badge that says "20 kr cheaper at another shop" is often wrong once a second delivery fee is added. Grand Total does the arithmetic that actually decides what you pay: item prices, shipping tiers, weight bands and free-shipping cutoffs across your whole list — not just the one product on screen. What it does - Identifies products automatically from the page's own data — no typing, no searching. - Shows a small badge on product pages: on your list, cheapest here, or cheaper elsewhere once delivery is accounted for. - A sidebar totals your whole list live, as you add to it. - On shops we can reach programmatically, offers to fill the winning shop's basket for you. - Works shop by shop: nothing runs anywhere until you switch that shop on yourself. Built for privacy No account, no login, no sign-up. Your list is addressed by an anonymous id stored only in your browser. A product lookup is answered and forgotten — nothing about what you looked at is kept, logged or shared. Site access is requested one shop at a time, on your say-so; nothing is granted until you add a shop. Currently covers Danish hardware, DIY and coffee retailers, with more shops added over time.
