I am building a ecommerce medical supplies site, with oscommerce, and i want it to have a multilevel pricing, that when a customer creates an account you have the default price, but we shuld be able to have multi level pricing, and we shuld be able to control each item to each customer, then also when the customer logs in it will show them on default there recent and common order list. again i am a web designer, and can work with more customizations as it will be needed. here are some links i wish my site should look like. not necessarily. <[login to view URL]> [[login to view URL]<wbr />.com/][1] [[login to view URL]<wbr />.com/[login to view URL]][2] <[login to view URL]> Thanks. ## Deliverables * * *This broadcast message was sent to all bidders on Tuesday Feb 12, 2008 12:57:58 AM: I want to chat with the bidders, about this bid
