As mentioned, the market you have entered is extremely overcrowded, margins are general low & you need to sell a lot to make any decent returns. However, if you can differentiate and make your business stand out from the rest you may have some luck with lots of determination and patience.
I founded TheCoolingShop.com in 2001 and sold the business in 2005 after 4 amazing years. One of our clients WaterCooling UK is a big player in the enthusiast market, therefore my advice would be:-
- Try and build and sell custom products and bundles so it's harder for your customers to price compare your offering. You want to sell solutions that help customers solve a problem and makes life easy for them, for example, Ready made bare bones bundles & barebones PCs kits.
- Follow the EBay route, find a product that works, ie makes good margin, and try to sell 10 a day of that one item. It will take time to gain traction with this, and it depends on your current eBay account status, feedback etc.
- Try to start small and expand from there, your choice of product and price is crucial
- Offer all eBay customers a discount code with their purchase, ie 10% off at your website.
- Over time your website will grow, but it will take time and clever planning.
- if you get known for hot deals, you'll gain a following, and people will start pinning your site on places like HotUkDeals, which can bring in 300 visits in one go (if it's a great deal). However don't be tempted to post offers on these sites yourself, you need genuine customers to spread the word.
- Don't overly rely on social media, it's really hard to get sales that way!
