We give them the option to register on the receipt page. That way there is no barrier to order.
Ive seen this method before and liked it. Basically I placed an order (I think it was 1800flowers) and after I was completed it sent me to a page where I could register. Also, in my receipt I got it had a link explaining the benefits of registering and when I clicked the link it took me to a page where I could then register with my email.
