SCF Auctions - Any Help Appreciated.

I am thinking of offering stamps,etc for auction.
How many days would you normally list items for?
How much does paypal charge in fees?
Would it be better if I listed lots @ $5+ rather than amounts under $5?
I know of another similar payments service to paypal,who I have emailed to ask how their system works. I think they only accept UK, USA, Australia & Pacific Islands currency.
Any help appreciated

The maximum days are 7
List what you want, how you want,
it must be value, or it won't sell
Possibly most like to see a fair range if they are "duplicates"
30-50 stamps say.
Decent scans.
I have bought and sold via paypal and had no problem thus far
you can determine currency within paypal account.
For an item of about $5 you'll pay 50c? I am not sure,
that's what I add to assist the vendor when I buy.

Hi Rod222,Thanks for your reply. I have a lot to sort out but I thought I'd offer NZ stamps first. I would have to look into the paypal first before I did anything.
While I have got you - I have started what some members refer to as a "Round Robin". I post stamps to A,who takes out stamps they like and puts in replacement stamps and posts it to B and so on until it reaches E, who then posts it back to me. I put it in the forum - contests, quizzes, and giveaways. I had a look at Buy/Sell/Trade but I could not see where it would fit. It's not selling - it's a trade as such but there was only trade wanted, not trade available. The only cost to a member is the postage cost to pass on to the next member. I already have 4 members interested. I just hope it's in the right forum.
many thanks
