When you receive new deliveries.
I have worked in buying nearly my whole working career, for people such as the Coopertive Wholesale Society, ELC, Findel, Shop Direct and Sainsbury's.
I have been very lucky, having a career that has enabled me to travel the world, working with forward thinking companies and meeting interesting people.
However if you work with products, the one thing you love best of all about your career is the arrival of new products. Seriously, its only through the products you choose to buy and sell, that you get to find out if you are any good at what you do.
So my office may well be a mess, but its because I have all these lovely new lines to go through and get up and running on the Smart as a Button website. Bring on the next few days, as I oooh and arghh over new buttons.
