I buy lots of 100 guitar pics/plectrums. I spend about 10£. Then split them into smaller lots. And list with free postage. U have to invest a little. Always get the ball rolling for me. Also puts money into PayPal which you can buy 1 p auctions with.
You have to lose a bit of money at first to build the account up. With that in mind buy any low risk item in bulk, split it and sell for a price you know it will easily sell for.
Invest some of your own money to get to 100 feedback within the first 90 day probation period then you are definitely good to switch to what you want to sell with a lower risk of being taken down. Just introduce whatever you want to sell slowly.
