I would not lower my prices, but I would have a sale every now and then. Also, you might want to come up with a catchy special, such as 5 for $10, 3 for $25, etc. That would lower the price some, plus the customer won't expect the lowered price each time. This also gives them a discount on buying in bulk. I'd hate to lower the price, then have to raise it right back up for some reason.
