Specialised acrylic displays along with slateboards and accessories, have enabled a far bigger product range to now be displayed in many Post Office sites, with specialist 21 tier card units being able to maximise sales from limited floor space. The introduction of "Open Plan" counters has also enabled the subpostmaster/mistress to be able to offer additional Post Office services, without the expense of a typical fortress type counter. GDP Design & Shopfitting are a nominated supplier of "Open Plan" counters, and have installed several at various sites across East Anglia & London.
