Goods are keenly priced... but fulfilment of orders is painfully slow!
I suspect the company carries stocks of only the VERY popular items - and relies on its wholesalers to expedite other goods as demand arises...
As I don't work for the firm this is just a guess as to why my order took close to a fortnight to arrive... If you need goods within 2-3 days I'd use companies like Screwfix or Toolstation - which both normally carry good stock levels and offer fast turnaround of orders...
