I was told you can purchase dot Mac accounts on ebay. Checking ebay I see there are accounts for sale and you may be able to buy at a discount. My question is, how does this work? What am I purchasing and where do these accounts come from, that the seller can afford to sell at a discount? I guess I just assumed with dot mac you pay Apple directly to activate your account. Please explain this to me. Is it safe to buy from ebay if I find a disount I like?
