Very large orders of wallcharts are shipped as flatpacks. Each flatpack contains 25 sets of one variety wrapped in heavyweight kraft paper. A minimum order contains 100 chartsets and you must order in multiples of 25. Each pack consists of only one variety but you can have a mix of varieties in the order eg 25 x TCM + 25 x Zen + 50 x CMB = 4 flatpacks
Smaller orders (4-8) are packed in sets of four and shipped as normal courier parcels. Larger orders (Qty>8) are stacked on a skip and packaged for delivery to your site. You will need to have a means to unload from the delivery truck.
Flatpacked wallcharts attract a very significant discount and are best suited for colleges, and resellers.
