The first quotation came in lower, so the brand placed the order. Three weeks later a supplementary invoice arrived for tooling, and a second for print plates, and the landed cost ended up above the quotation that had looked expensive …
Two adapter programmes are quoted for the same output. In the first, the connector is described in a drawing note - "5.5 x 2.1 mm, centre positive" - and the sample arrives matching the note. In the second, the connector …
The most expensive laptop charger fault is not the one that fails. It is the one that works at 60W and was sold as a 100W product, because the customer discovers the shortfall weeks later, on a laptop that never …
A branded phone charger programme can open at 200 pieces per model - and that number, not the unit price, is usually what decides whether a first channel test is affordable. The same opening quantity applies to a bundle or …
