The exchange of buying and selling has been around for a long time. Nowadays, the internet appears to be the hub of just about everything. And there are various methods to buy and sell online.

Whether you’re collecting gift cards or exchanging furniture, getting to know how to buy and sell online is an important skill. As eCommerce grows, you should familiarize yourself with the various available platforms.

The Basics

At first glance, the basics of buying and selling goods online seem straightforward enough, and you don’t need any kind of academic qualifications or experience to get started. For instance, you can buy things at a discounted price and resell them for a profit, either as a part-time side hustle or a full-time job.

However, it’s easy to mistakenly assume that you’re bringing in more money than you actually are. Online tools can help you manage the financial and logistical aspects.  You should take into account possible additional expenses such as marketing and transportation costs. Furthermore, you may need to consider renting or purchasing an office or warehouse as well as hiring employees. Finally, you’ll need to find the right platform to be the basis of your business.

Platforms to Buy and Sell Online

There are several eCommerce platforms where you can buy and sell online.


The first one we have on the list is Amazon, by far one of the most popular online platforms globally, and you can buy or sell nearly anything. You can buy or sell nearly anything, so you will always find new products and brands.  The best part as a seller is you’ll get 5% back on your first $1,000,000 in branded sales.

On the other hand, as a buyer, Amazon provides easy tracking for any purchases. Besides including a history of the order details, it helps you track the item’s arrival, even if there are different delivery dates for multiple purchases. Additionally, they will help you find a package if it goes missing during delivery.


Selling items on eBay is easy. With millions of buyers online, it’s not difficult to list your products and reach potential buyers. Plus, it offers up to 250 listings with zero fees, and you can quickly get more listings if you have an eBay store. The 24-hour eBay support team allows you to sell confidently, as they are there to implement policies and resolve any issues.

When it comes to buying, you can get anything from tech to fashion and home appliances to garden accessories at great prices from eBay. This platform offers daily deals where you can get your favorite items at affordable prices with discount offers. You can also find seasonal sales in their sales and events section.


Etsy is a popular marketplace for selling and buying extraordinary items, from handicrafts to vintage items. With just 20 cents, you can become a seller on Etsy. As a benefit, Etsy pays for your Offsite ads, and you only pay a fee if you sell anything through ads. However, a potential downside is that Etsy takes a small amount as commission and charges a standard payment processing fee when you sell any items.

With their search tool, you can explore extraordinary products and find many custom-made gems. There is also a journal with editors’ picks that offer amazing trends and ideas in the marketplace. If you have questions regarding purchasing, shipping, order issues, etc., there is plenty of assistance and guidance on the website.


Shopify is not only for sporadically selling an item or two; it also allows you to create a more established online store to present your brand and products to potential buyers. Plus, you can promote your product and sell it online via many Shopify sales channels or turn your followers into customers from Facebook, Instagram, TikTok, and YouTube.

Besides, you’ll have access to a huge marketplace, “Handshake,” which offers the best US brands. Here, you can directly deal with the manufacturers and not the resellers. Plus, you’ll always be updated about the product launch and never miss out on your favorite brands. In addition, it’ll provide information about recent trends and brands via emails.

Popular Methods of Buying and Selling Online

If you don’t have an online shop, you might be worried about getting started, but there are plenty of alternative methods out there.

Buying From Wholesaler

Start by buying in bulk from wholesalers at a low price. Then, you can turn a profit by selling those same items. This is the ideal way to get more reach to your customers. However, this strategy requires a rather large investment with a lot of work and risk.

Knowing your customer and market is crucial when collecting bulk items, so you avoid having unwanted items in stock. Therefore, do your research, and buy the best-selling products in bulk. This way, you can get maximum profit and turn your buying and selling into a full-time job.

Buying From Manufacturer

Buying from a manufacturer is more profitable than wholesale because it removes the middleman. Wholesalers will include the profit margin and shipping cost in the end price.

Therefore, buying directly from the manufacturer can save a lot of profit margin and offer you advantages over other retailers. In addition, some manufacturers allow you to add your own label on the products. Which is a good business practice and helps to promote your brand.

Dropshipping Products

While buying from a manufacturer can be great, it can’t always be cost-effective if you are on a budget. The dropshipping method allows you to accept your customer’s order without needing a warehouse. Simply start by picking the product you want to sell online and find the supplier that offers dropshipping at a reasonable price.

Then, you’re ready to post your items on the marketplace at the price you set. Moreover, you don’t need to worry about packing and shipping items, as your suppliers do it.

The best part is you don’t need to pay upfront. This means you only pay after your customer pays you. Furthermore, you may be able to get the items in bulk to get the wholesale price. Because buying one product at a time can cost more and is helpful until you’re a reputed reseller.
