I was struggling with finding products to promote on my hiking dropshipping store, and I was losing money on advertisement with no returns, I gave E-Sniper a try, it really helped me out a lot.
There are a few options similar out there, but the best part of E-Sniper is that you get extremely detailed reports about how to target for your Facebook adverts and the icing on the cake is that they give you the link to other successful ads on Facebook that you can analyse yourself.
E-sniper is worth much more than I paid.
I STRONGLY recommend E-sniper to everyone who's interested in running a successful dropshipping store!
I don't always clop, but when I do, it's because of E-sniper.
