Which is the hottest place to have a bargain in Central London this year?

The casual shopping to see around is something that I always take time, looking for that perfect black leather handbag? looking for a laptop bag that will last? the best bargain time in London is the summer the sales in the main street goes to heaven for shopaholics, expert and amateur buyers, I usually put myself in between all those categories : when i start buying sometimes i loose myself but do not try to sell me a leather bag there i draw the line and suddenly Iam the most petty detail picking human ever existed.
