I'd have to agree with dwmgoods35, their items are priced a bit high especially if you buy per piece.
But they are a pretty legit supplier and have been in business for roughly 10 years. They also accept safe payment methods.
If you have enough money to spare, maybe you can try getting one their wholesale packages, like the first package you get 30 sunglasses at roughly US$26++ each. Although, having no experience selling sunglasses I'm not quite sure if that's low enough for you to make a decent profit.
Anyone who's bought from them? Maybe you can share your buying experience with us all. Thanks in advance.
