Let's try to find interchangeable indonesian numbers products not among a large group, but within the product. For example, one burger will have two patties, and another will have three, the third will have buns of different colors, and the fourth will have a pair of cheese slices instead of one. And despite the differences between the items, the buyer will still consider these products interchangeable.
Increasing sales of interchangeable goods
A simple conclusion follows from this: if you want to sell burgers profitably, you should show the uniqueness of your product. With the right emphasis, a person will buy not a cheap one, but, on the contrary, the most expensive and promoted product. As you have already guessed, this is not difficult to do: add a specific sauce, more meat, vegetables, offer a product from the chef.
In fact, this example is quite primitive, but in general the trend is clear: you should, based on the interests of the buyer, try to fully satisfy his needs.
In some areas, it is quite difficult to make a product completely interchangeable. A striking example is a beauty salon. It is quite difficult to justify a high price here, but try to create a unique selling proposition, position services, promote a brand. But even here, professionals try to sell services at a higher price, dividing haircuts into complexity categories.
