No, you will see less sales, because you get more "exposure" when items
end and you list them as new. So with the GTC there isn't that
"activity". Older items do not show up in searches as much as new items
do.
I've had no sales in 45 days!!! I have over 400 items and nothing...no
even emails from buyers who want to offer 50% or less than my sale
price. YIKES! what is happening?
