this is a quick guide on seller fees as i see it so many times!!
DO NOT list anything for £1.00 as this will cost you 0.20p next to listing something for 0.99p which will cost you 0.15p
i know this is basic but you would be suprised how many times this happens
check out ebays fees as it works for £5.00 and £4.99 also
i know it's only 5p but its better off in your pocket!!
