Definitely Amazon,more variety.
For variety and low price of product Amazon is better.
'the bay' for me, more just habit I guess!
I usually sell on eBay and buy from Amazon
i buy and sell on Amazon as i really don't like sites that if i pay by paypal i have to fill in their form for address etc when all the details should be on the paypal payment email send to the supplier so that is my biggest bug
I do not care whether I buy from ebay or Amazon, to me the price and the quality of the item being sold is of utmost importance. I strictly check on reviews because i love quality and good service. Sometimes i am led by specifications. If the specs are ok i buy.
