Mumsnet Talk

Hi all, I have now been buying and selling from carboots for a few months and it has gone ok, learnt a few lessons along the way. I was thinking now I'd quite like to make it into more of a business and expand a bit.....I just dont know where to start! My husbands customers friend buys stock from shops closing down and sells on ebay and seems to do quite well but how would one find out about such shops. Also, how would I go about buying end of season stock or would wholesale warehouses be a better bet? Any advice would be very gratefully received!
