i make a buyer acc and i list my item the same day a NO NAME NO brand item start the bidding at like 11.00 with 3.00 shipping it does not even matter if the item even sell this is what i call a test auction i make the auction 5 or 7 days when this listing ends i will sell what i sell from that ending day. don't waste time buying an item because that acc might get a mc999 or something ells. hope it helps. i have made a lot of acc and i have had seller acc the feedback was over 300 and i have never bought anything.
It's generally better to have some sort of buying/bidding history on your account prior to selling otherwise you fit the pattern of a high risk seller.
I have done both. EB seems to be making it difficult to just list straight off the bat. I think at this point I would age it a lil and do some browsing. Maybe a lil bidding too.
Funny question, as it reminds me of years ago you had to be a buyer first, as you were not allowed to sell until you had so many feedback.
I still do both on my accounts. Some I start off selling and others buying, but that is a personal thing where I try to stop myself getting into any patterns that create laziness in my habits.
Must be SELLER or BUYER first?
