Single, pack or set? Check the order unit before choosing a quantity

“I need 30” can mean 30 individual fittings, 30 bags or 30 packs. Before placing an order, separate the number of pieces you need from the number of sale units you are buying. A product photograph, supplier carton or warehouse stock total cannot settle that question by itself.

For a current example of a page with separate sale options, see the listed WA108P ceiling box: Single and Pack of 10 options. Select the intended option and check its details before choosing the quantity. Confirm the actual supplied model and contents with APM if those details determine your order; this example explains the selector, not suitability for a particular ceiling or accessory.

Quantity multiplies the selected sale unit

If the selected option is explicitly confirmed as a pack containing ten identical pieces, a quantity of three means three packs: 30 pieces in total. It does not mean three individual pieces. Conversely, selecting Single with a quantity of three means three singles.

Need 23 pieces? State both the requirement and the proposed split

With a ten-piece pack and a separate single option, an illustrative split is two packs plus three singles: 20 + 3 = 23 pieces. That only works if both sale options are offered for the same required item and APM confirms that split is available. Do not round up or substitute a different model without deciding whether the extra pieces or changed specification are acceptable.

For a mixed materials list, put each model and size on its own line. Write “23 pieces required” first, then the proposed pack split. This keeps the requirement clear even if the supplier needs to offer a different permitted sale unit.

A supplier's bag quantity is not automatically the shop's sale unit

The Embrass Peerless 15mm compact compression tee is another useful example: check APM's product details and confirm the quantity being supplied. A manufacturer’s catalogue bag or carton quantity does not, on its own, establish what one retail order unit includes. The genuine single-fitting photograph above shows the fitting, not a sealed bag or its contents.

Compare prices on the same basis

When comparing a single and a confirmed multi-pack, divide the pack price by its piece count to calculate a price per piece. Compare the same model, tax basis and included contents. Check any delivery charge separately; a lower price per piece does not by itself establish the lowest total cost for the quantity you need.

Also distinguish a pack of identical pieces from a kit or set of different components. “Ten-piece set” does not necessarily mean ten interchangeable replacements.

A clear quantity enquiry you can copy

Send your list or a clear photograph of the label to APM. Call 020 8702 8080 or 07737 263641; WhatsApp the shop number or the company mobile. You can also use the APM contact page. Record stock is not confirmation of physical or allocatable availability.

For recurring jobs, keep the confirmed sale unit alongside the part number in your property parts reference sheet.
