I can certainly appreciate what your saying there but..
I am a metal merchandise shop, i don't sell new release Cds or DVDs, Video Games generally and i don't sell TVS or hi fi equipment etc or top 40. I don't really know what the competition is there with the retailer you mentioned we don't even sell any of the same things. I ship to Israel, Norway, Germany wherever, virtual staff and don't have a physical retail store I don't see any similarity or competition aspect. I would consider competitors to JB Hi Fi to be Harvey Norman or even Ebay etc not a niche market online seller like myself who sells Behemoth shirts, cannibal corpse patches, Opeth flags and Motorhead fridge magnets or Dimebag Darrel Statues to rock and metal fans..
My comment were coming purly from a 'consumer' aspect, i much prefer to shop online these days, i am over waiting in line at checkouts and haven't bought retail for a long time, prefering online experience out of personal preference..
I really didn't start this post with the intention to plug my shit or knock any competition - just curios to see the buying habits and who still bought CDs and in what formats, why and where from. I reckon online is the winner, due to economic factors I pointed out, and is only going to get bigger but thats for the consumer to decide not me, you don't get ahead by dragging others down thats for sure.
Thanks for your comments though I will be more humble in the future.
