I'm not in the biz, but here's a few suggestions:
- When you are evaluating a drop shipping company, ask for some references. Go to those websites and scan for any complaints related to shipping, wrong items, damaged goods. Anything that may tip you off that this drop shipper may have issues.
- Before you sign up, go to one of the reference sites and order a few things you know will come via the drop ship company. Do several orders - weekend, Monday, Thursday. Time how quickly your goods arrive - and double check item accuracy and condition. A little real life testing never hurts.
