Why do two suppliers quote different prices for the same product? Often one has included the rails and shelf and the other has not: a catalogue page presents a product as a whole, and not every part in the photograph is in the price. On the GEBHARDT Isotec TBX page the base (castors or pallet), plate rails, intermediate shelf, freezing rack, drip tray, document pocket, extra pulling and lifting handle, external thermometer, colour and logo are named separately.

ItemWhat to ask in the quotation
Base: castors or palletWhich variant was priced
Plate railsQuantity and how many plates
Intermediate shelfQuantity; the grooved tub for shelves is chosen at the start
Document pocket, external thermometer, pulling handleIs it in the price

Write the items you need in one column and tick each quotation against it; the empty cells are your question list. GEBHARDT states that plate rails, intermediate shelf, document pocket, handle and external thermometer can be fitted later, while the grooved tub needed for shelves is chosen when ordering. Ask Aris Makina for the item list in writing; we obtain it from GEBHARDT and pass it on. Attach the approved table to the order and check every item against the same list on delivery.
