That’s business, I’ve got to make £x grand a month just for this place to break even, you don’t make 5% of that a day (working on a 20 day working month) and you don’t make it equally from every sale.
I mean we try not to lose money on a sale, but we do sometimes, nature of the beast a 15% margin can get eaten up by shrinkage, labour, bad debt and all that, sometimes I can make my whole months target in a single sale, in fact sometimes I can make a few months target in a single sale.
I could make a lot less on those of course, pass on every penny of every special deal from our supplier onto our clients, or frankly say “You know what, the ‘market’ values this at this but in fact that’s 300% of what it costs, I’ll charge you half that” and I’m sure I’d be welcomed back with open arms every time, but sadly when I say “The ‘market’ only values this at this, but that’s only a 5% more than we can buy it for, sorry but I need more than that” they suddenly remember that don’t need it any more and buy it from somewhere else – Apple stuff mostly.
