Some sellers don't want to increase their product price. Perhaps because they have pricing agreements (eg. Royalties of some percentage of the sale price). Perhaps because for a higher price the customer expects a better product. (Nobody complains when the $1 scissors don't cut great, but the $15 scissors really ought to cut properly)
