You figure, John?
Even after costs for staff to answer phones, deal with web enquiries, the website costs themselves, advertising, staff and equipment costs for cutting all stock in two foot lengths, fluctuating metal costs, facilities rent and all insurances, staffing admin costs ie payroll/ tax accounting, security costs, packing costs, shipping/postage costs, and the inevitable shipping/mailing losses, returns, the odd dissatisfied customer, staff time to deal with all the losses, returns, disat cust etc.?
Not saying prices don't seem a bit steep at a glance, but costs in the metal pack game could mount up rapidly and if you aren't counting all the costs + profit all the time to figure a valid price for piece goods, you are going out of business.
Go for it, but it could be more complex to make steady money at it than you think.
