Another shipping question. Client wants to have free shipping when two or more bottles of product are purchased. As well, this is to kick in a 50% off all subsequent bottles of sauce. So two bottles at $6 each for example = $12 but free shipping. Three bottles at $6 each equals $15 and free shipping. Six bottles = $24 and free shipping, etc.
Out of my "design and CSS" skill set. Any pointers? Thanks!
