I placed my add on a Thursday morning with the hope of geting it advertised across the sites for the weekend. Desperate Seller promote the idea of getting it to 101 sites within 24hrs. Early the next week (after having no calls apart from people wanting to sell me something) I checked some of the sites at random. Of the 5 sites checked my advert only appeared in 2, a 40% success rate. After submitting my query to Desperate Seller indicating the 40%, chasing after over 24 hours, they finally came back saying they would check to see why it was not appearing in the 3 I checked. To date 92 days after saying they would look into it) no feedback & my advert still appears in few sites!
It seems as they have no system to check whether they do as they claim & rely on you checking to see if the advert has appeared. At £29.99 its only value for money if it works though you'll have to spend a lot of time checking the individual sites to see!
