Sales are funny things, we tend (as a wee shop) not to buy too much in so we never get left with anything in real quantity like the bigger boys.
We do however pick the wrong item to buy in – usually the wrong colours etc – which we sell through gradually.
Plus… things like clothing, we only do Gore at the moment so we don't really need to get rid as it stays current longer and it saves us churning stock over just as an exercise in revenue generation. Sale prices destroy our margins so it makes commercial sense not to get into the situation where you have massive stock overhead and rubbish revenue from it at the end of season.
Our 'sae' is just spread out over the year as we sell things through and look after good customers and welcome new people in with good pricing and good service. Seems to work better that selling stuff for pennies.
Anyway, i am twaddling.
