What goes wrong
Count the heavy or stacked orders.
Packaging Boxes lists Double wall boxes for this line. Heavy lines and removal loads decide the quantity. Everyday single wall does not.
The check before you reorder
Say double wall and the size.
Store it apart from single wall. The board looks similar until you lift it.
Dispatch on that order
On Packaging Boxes, put Double wall boxes on the order with the lines it belongs to, so you are not paying a second delivery for the piece you forgot. Free UK delivery starts over £50 ex VAT.
