I need to know if there is a readymade Contribution at http://www.oscommerce.com/community/contributions/ or if I need you to make a new one for me. Details: Collective Sale I need to make a sale that will be active only if a minimum number of customers will buy the product on certain time period. I need to have quantity number of products and end time. I need the option to lengthen the time period and/or the quantity number. Please give me price for that if it can't be found freely at oscommerce website. Thanks in advanced, T.B
