Guys I got a question

I want to batch download this URL but for 3 variables

It should run through

http://list.mall.taobao.com/50025135/g-s-----80-(*)--50029627-x.htm?start_price=0&end_price=20

(*) for 80 - 240

and then move on to

http://list.mall.taobao.com/50025135/g-s-----80-(*)--50029627-x.htm?start_price=21&end_price=40

and download (*) for 80 - 240 again

and so on and so on

How can I do it using the batch downloader function?
