It's a question I've been thinking about since launching my own e-commerce website using Ali-Express.
Whenever I see a product I like online, I'll usually have a google around to see the best prices for that product. If you're listing for example a gaming headset on your website from Ali-Express, I google that headset to see if it's a good price, I stumble upon Ali-Express selling the same product, same shipping times for much less.
Are we supposed to assume people don't do this thing and buy immediately? I guess it would be easier with a piece of jewellery, but with a branded bit of Tech for example, how does one overcome this potential issue?
