Is your price too low?
Be careful when you fix the price for your product. If your price is too low, people will think that it's not worth it. And if the price is too high, they'll go for something like yours at a lower price. You have to find the perfect price that will make the sale.
A good thing would be to visit your competition. See how much they ask and what they have to offer for it. Then, you can take a look at what you have and you'll have a good idea of what you can ask.
Lower price is not always a good thing. If your product is great, you don't need to lower your price. And if you raise it from time to time, then it'll build a feeling of better worth. And so even if you didn't change much in your product.
Price is something you should take some time to think about. Too high and people will not buy. Too low and people will not buy.
