The items are "on average" half price, and more than 1,200 parts are listed, primarily for pre-2000 stitchers, binders, stackers and mailroom kit.
"We've slanted this sale to users of 'older' kit to encourage them to use genuine parts," said technical director Martyn Snoad.
The parts are non-returnable and customers must state when ordering that the spares are part of the promotion.
