how soon should i make sales

if i submit new free sites or gallery pages how soon do you think i should make sales from these sites?

at the moment i am making sales about 2 or 3 days after i have built and submitted my sites and i am wondering if this is normal or not sometimes i have built a site that has not made a sale for about 7 days after it has been built and submitted

A lot of the time you won't even get listed for days or weeks, so its normal.
