can any one advise me how to formulate a curl command with the relevant info which will return the page containing the price offered for the dvd ?

any help at all would be appreciated

They use javascript, form variables, and cookies in combination. Does not look straightforward.

curl --data "ctl00%24ScriptManager1=ctl00%24upGetValue%7Cctl00%24btnGetValue&ctl00%24txtBarcode=871741824227&ctl00%24ContentPlaceHolder1%24hndMinItem=10&ctl00%24ContentPlaceHolder1%24hndMaxItem=500&ctl00%24ContentPlaceHolder1%24hndMinPrice=&ctl00%24ContentPlaceHolder1%24hndMaxPrice=&ctl00%24ContentPlaceHolder1%24hndMaxSalesRank=&ctl00%24ContentPlaceHolder1%24hndMaxDupItems=1&ctl00%24ContentPlaceHolder1%24hndGridItemCount=0&__LASTFOCUS=&__EVENTTARGET=&__EVENTARGUMENT=&__VIEWSTATE=true%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&__ASYNCPOST=true&ctl00%24btnGetValue=true" hxxp://www.webuydvds.co.uk/start-here.aspx

Use the site like you would a web browser.

Visit the main page, let it set and keep cookies, get the relevant hidden variables, send the cookie when you make the POST.

any heads up or pointers on how i accomplish that ?
