I didn't log in, I was a guest. It should remember for guests too, that way if I add a few things, come back a week later to make my order, have to recreate and forget to add something, you lose money and it's a pain for the guests.
It might be too much hassle, if it's cookie based for guests and database based for registered users. You can always change the cookie expiry date though.
I will order stands, when I get to it, my next wedding's ages away though. You would't happen to have a small portable seamless background would you, suitable for babies or kids? I'd like an adult sized one but they'd be too big and heavy to carry around I think.
