Ill try and be as constructive as i can, have a look at http://www.computer2000.co.uk They're apparently the distributer/wholesaler a lot of internet based companies use to supply IT products. From the looks of it you will need a registered company, and VAT registation. These will be needed for any wholesale supplier imo, having dealt with wholesale before but not in computer parts i can say its fairly easy to get off the VAT registration if you contact them and explain your a start up, But 9/10 you WILL need a registered business. Ive noticed that places like ebuyer are now offering discounts on multiple buys, but the savings are so small it isnt even an option imo, For instance a 1Tb samsung F3 is £63.87 inc VAT for a single drive but if you buy 200+ the price drops to £62.98 inc VAT per drive so an outlay of £12,774 nets you a discount of £178 Like what has already been said by myself and others, Its far to difficult to establish yourself in the market today without £millions of startup capital.
