SCK4 is Amazon's inbound cross-dock at 6001 S Austin Rd, Stockton, California — the building our United States freight is delivered into. SNN4 is Amazon's fulfilment centre at Baldonnell Business Park in County Dublin, the first of its kind in Ireland, and where our European stock is held.

We took the name because it is the honest description of how we operate: our inventory lives inside one of the largest fulfilment networks in the world rather than in a unit of our own. The code on the door is the code on the box.

Our freight is consolidated, palletised to Amazon's inbound specification and booked into an appointment slot before it moves. In the United States it is received at SCK4 and distributed across Amazon's fulfilment network; in Europe it is held at SNN4, a fulfilment centre where stock is stored, picked, packed and shipped.

From that point orders are picked and dispatched through Amazon's fulfilment network, usually 1–3 business days after payment clears. That is why your order may arrive in Amazon-branded packaging — the box is packed in an Amazon fulfilment centre and travels on its delivery network.

It also means we do not quote a delivery promise we do not control. The delivery estimate at checkout comes from the destination you enter, not from a number picked because it converts better.

Holding stock inside the fulfilment network rather than in a unit of our own changes what we can do. Breadth becomes affordable, because we are not paying for shelf space that sits idle between seasons. Multipacks and case quantities make sense, because the picking cost per unit falls rather than rises with volume.

That is why the catalogue spans performance nutrition, first aid, foot and oral care, cooling, pet and household rather than one narrow shelf. What unites it is not a product category — it is the moment of need, and a supply chain that can carry a long tail without the economics collapsing.

We sell at trade prices with a minimum order of $2,500 (US storefront) or €2,500 (EU storefront) of goods. Workplaces, hospitality, facilities teams, event operators and resellers order the same catalogue, with consolidated delivery and invoicing.

Larger or recurring orders can be quoted individually — use the quote form on our business page and a person will answer with written pricing and delivery terms.

Every product we list is a genuine, new product from the brand named on the page, bought from the brand itself or from an established distributor. Each carries our own SCK4 reference so it can be ordered and traced precisely.

Brand names and trade marks belong to their owners and are used to identify the products; listing a product does not mean its maker endorses us.

We are not Amazon, and we do not claim to be. SCK4 and SNN4 are Amazon facilities, owned and operated by Amazon; our relationship to them is that our stock is stored and fulfilled there. Anyone telling you a seller is the marketplace or the warehouse it uses is misleading you.

We do not make medical claims. Supplies and supplements help you prepare and recover; they do not treat or prevent illness.

We do not publish reviews that are not attached to a real order, and we do not run countdown timers or invented stock scarcity.
