Since you're here, could you please get your site to remember my choice of sort order, from one page to the next?
I'm in the habit of using "sort by price", but your site is one of the many that don't remember my choice, so I have to do it to each page I visit - which means loading each page twice, more click fatigue and more rapid loss of interest, so less chance of me actually buying anything. It also means more load on your server, especially if a lot of people do it.
So far, I haven't bought anything from your shop, and that's partly because I'm extremely impatient, and just get tired of having to choose the sort order over and over again.
It doesn't have to be done by a cookie. You can just use a session variable, which persists long enough so that I wouldn't have to tell it twice in the same visit.
