Ongoing Shopify Plus work for London's couture fragrance house: gifting, international delivery and a cart that stays right.
Miller Harris's cart does a lot: gift wrap, gifts with purchase, free samples and delivery to many countries. I look after their Shopify storefront, and I rebuilt the gifting flow so all of it works together without wrong prices or glitches.
Miller Harris is a British fragrance house, founded in London in 2000 and known for its couture approach to perfumery.
“We have worked exclusively with Graftstudio on a series of Shopify projects over the past twelve months. Richard has been nothing but forthcoming; he's reliable and quick, even at the toughest of times.”

Gift wrap, gift-with-purchase offers and free sample thresholds all touched the same step before checkout.
A change in one place could show the wrong price, or add and remove products in the wrong combinations.
Delivery messaging didn't change with the shopper's currency or region.
I started with free gifts in the cart, because that's where the most features meet.
A custom picker in the cart drawer that checks stock, keeps prices right and stays steady on screen while the cart updates.
Wrapping paired with its ribbon, so the two are always added and removed together, in a layout that holds up on mobile.
Delivery messages that follow the shopper's currency, and multi-store support so the same features run in every region.
Ongoing maintenance and refinements as the store grows.
Customers get a clear, reliable gifting and delivery flow wherever they shop from, and sales are up 12% since the new gifting flow went in.
I do. I'm Miller Harris's fractional Shopify Plus developer, and most months that means Shopify Functions for their ongoing gift-with-purchase campaigns, built by someone who already knows the codebase.
