Before ordering for products online, you must have known How to know which products can sell in your environment (you can read through source).

Knowing the right product to order: i will go brief on this, it might be in you surrounding that you find something lacking and its what people are eager to spend on. Recognize these products and make a move to make money with it.

Recognising the right store to order from: there are many stores orders can be placed online but I use and recommend only one, Aliexpress. Aliexpress is the best so far for importing products into Nigeria.

Searching for the product: This can be done easily, locate the search button or get your products through the categories menu which can be found at the left hand side of the site.

Knowing the right suppliers: this is an easy task, I recommend going for suppliers with not less than 98% rating. Check for their order numbers and feedbacks too. After knowing them,

Contact the supplier: every thing as been made easy on aliexpress, you can contact the supplier while on the site, send a message to the indicating you are buying this kind of product and if there is any discount if bought in bulk.

All you need here is a valid response from the supplier. Then,

Placing your order: now that you have done the previously mention steps, continue to ordering the product you want. Select the quantity and proceed to checkout.

Checking out: this is a reason why I like aliexpress, its her user friendly interference. You can use your credit card or PayPal to checkout, its save,fast and secure.

Delivery duration: This is where people make mistakes, if you are ordering a free shipping product, you are expected to receive your product in 28-30 days. But if its a paid shipping, you get them faster, all delivery duration are found on product page. 

If you are ordering in bulk, you can negotiate with the supplier to offer free shipping and if you can afford this, go for paid shipping. 

Tracking orders: nobody will pay for a product and not want to know how good its performing, you can track your good on aliexpress. 

Goto my orders>> Click on the order then tracking details. Copy the tracking no into your product delivery company's tracking field.

You can always return products if in bad order when you receive them. There's a return policy for that on aliexpress.

Advises:

Always do enough research on what products to order so as to make good sales and be at no loss.

Don't give high price tag for products you bought at very low price, not everyone can afford that. 30%-60% is okay. Well this also depends on wants.

Order for less products at first before making huge bulk purchases.
