Just had a thought, thinking more towards the companies in the uk selling Trad window cleaning supplies, do you think their is much of a markup or profit to be made? Originally i thought not, but through one of the suppliers i use, i notice in less than a month they had obviously gone through about 1000 invoices, which must mean there is clearly lots of business to be had and potential profit.
Random topic i know, but considering i used to be in online retail i just wondered if their was much of a market/profit for it.
