I have just listed a couple bundles of girls clothes, i end mine between 7 and 10pm and i use loads of pictures and close ups, i use a web site called photobucket to cut and paste pictures onto my listing, you can put as many photos on your listing as you want and it does'nt cost anything (not like e-bay picture prices) i also iron all my items before i take my photo's.
I try and sell 15-20 items a week (im clearing out the loft)
I think the postage costs put people off of buying bundles and its worth selling the good bits on they're own or on MN.
