Re: new online hookah store!
Yeah as Hajo has been saying try to be as unique as you can, try to have something that makes a remarkable difference between you an your competence. For this you should do a little research or study about the market you're about to enter, to know wich are the most common products, a range of prices of them and how big is your market (you don't want to have a sea of products that you can't sell or takes a lot of time to sell, as you don't want a ton of orders you can't provide because you don't have the physical product in your warehouse).
These are just some of the basics you have to assume and understand to become a unique vendor, go as deep as you can in the market to find how can you be unique and have the breakpoint between you and your competitors, try to follow hajo advices in products range. As you're not in the american market maybe selling SB or tangiers is a nice idea because as I have seen the european vendors doesn't have this products. So keep working hard I hope we can see you in the market soon man!
