Generic products in a mature industry, where the mark-up (or profit) is very small are not good for Tipzu.
The best products are those that are not readily available. You can't make a lot of money selling generic guitars, for instance, but you can if you sell hard-to-find models or custom-made instruments.
Look for boutique suppliers (the web is a great way to do this) - there are many, many garage businesses around the world making one-of-a-kind products. Aim for a 50% mark-up.
