Ok . So here is the deal . My band is having a CD release party on October 18th , in Central PA . We got a gret cover band to follow up the night , and a guitar hero contest with actual prizes ... Cd 's will be $ 5 with paid admission , door is $ 5 and some of the proceeds benefit a local fire company and K-9 unit . So far , we have the backing of the local Rock radio station , and will have live remotes from the show , door prizes , advertising on the radio for a few weeks prior , and other stuff to sell ... We want to get a lot of people in the door .

What may be the reason for their price promotions ?
They want to attract a larger crowd of people .
