It's the week of Blue Monday, so to try and perk me (and you all) up a little bit, I've decided to write a post on the best part of January: the sales. Amidst the dreary weather, dark afternoons and metaphorical belt-tightening, we're faced with a glimmer of hope. Every time I walk through the high street at the moment I'm bombarded with an array of bold, in-your-face signs, screaming 'FURTHER REDUCTIONS', '50% OFF', 'SALE CONTINUES' and the suchlike.
