Quite a lot of views on this service throughout the forum, some like to push them, others think they are a waste of money.
Best you use the 'search forum' on the sidebar menu to learn a lot more before deciding, however I would also suggest you talk to jg42122 before I made any decisions, he may well have a good alternative option for you.
Planes is another that has just kicked off a drop ship service, he would also be worth while taking a look at.
Cheers
