You need to find out rather or not the vendor has photographs available of the product they are really selling. When you're shopping face-to-face, you have the option to look at products close up, hold them in your hand, and study their texture. When you are shopping standard tripod and camera screw threads. online, photos are the closest thing to that particular there is. I would not recommend buying from any on-line goods shop that doesn't show pictures of the product. You should research the online goods shop's shipping policy. How much can shipping be? Is it free? If it's free, will it have an eternity to arrive? If I must pay for it, when can I anticipate my purchase to arrive? These are all things you as a consumer should know, and you can usually easily find the answers to these questions by find a "Shipping Policy" or perhaps "FAQ" page on the site. Previous, but certainly not least, you should find out what forms of payment this website accepts. This seems like it will be obvious, but I aren't even count the times that I've found a wonderful quality product on a site, only to find away that they don't accept any of the forms of payment I have available.
