Well thats why you would have to check your production price if you can Sell them for a lower price and still be happy with the profit margin then I would say do it. People always like a bargain. You could also try offering a 2 for something deal. Like for example you could sell them for 40 or 2 for 70. You could also put up a sign that says Limited Quantities Left. Sub- consciously makes people think that they have to buy now because there might not be any left later.
