You need to find out rather or not the vendor has photographs available of the product they are really selling. When you're shopping personally, you have the option to look at goods close up, hold them in your hand, and study their texture. When you're shopping QSMOTOR 12inch 3000W 72V 70kph Hub Motor with EM72100SP controller and kits for electric Scooter online, photos are the closest thing to that there is. I would not advise buying from any on-line goods shop that doesn't express pictures of the product. It is advisable to research the online goods shop's shipping policy. How much can shipping be? Is it free? If it's free, will it take an eternity to arrive? If I must pay for it, when can I expect 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 simply by find a "Shipping Policy" or "FAQ" page on the site. Previous, but certainly not least, you need to find out what forms of payment the site accepts. This seems like it could be obvious, but I simply can't even count the times that I've found a wonderful quality merchandise on a site, only to find away that they don't accept any of the forms of payment I have offered.
