Couple of questions... Do you subscribe to the free or paid version? I do the paid version, and get notification as soon as a shop is put up. A lot of times it makes the difference. Also it is easier to have a one stop place for all my shopping needs. When companies pick up new accounts, having the site gives me quick access and knowledge of the shops. JobSlinger has made me sometimes 200-400 more than I would have made, being subscribed to over 200 companies. 51 of them are regular through JobSlinger. Also when the quickly grabbed shops come out, having the paid version has helped me to get them before others on occassion.
I like the service. I know many equate this to paying to shop, but I do not. I consider it a tool, like a car is one. Sure, I could just do shops within walking distance to me, there are plenty, but JobSlinger has shown me more jobs out there than I have time to hunt. This is a business to me and I count JobSlinger a business expense. So much so, I deduct it every year.
