I like the ease of ordering, and the pricing, but on both times I have used the service I have felt confused at the point of submitting the order because the details are gone from screen before you commit, which on this occasion has led to me not getting what I really wanted.
Strengths
Confirmation page on order system to show what is being ordered. By the time you hit submit, the actual order details are no longer visible. You can't even review by hitting'back' on the site.
