Dropshipman: Easy Dropshipping

Having tried almost every other app in the Shopify store after the loss of Shopmaster, this is the closest one in terms of functionality. I had a few teething troubles but the support team (especially Sonia) have been awesome and quashed the bugs. There are some minor issues like not being able to delete a dead order and the admitad integration is a little clunky, but the important parts such as tracking stock availability and orders is rock solid. I highly recommend this if you have an established store with products and are looking for a new app, the ability to attach your existing products to listings saves time and works (unlike some competing products). The ability to override the listing with a new supplier is also a key feature, this allows your existing listing to keep it's reviews, google impressions and such. It was great when it was a paid for app, it's even better now it's free. :)
