If you've signed up for an account with us recently you'll notice we now ask for the date of your wedding(if you know it). We're not just being nosey, what we now do is send you a little email 10 days before your wedding so if you've any last orders before the big day you can get them in on time.
Part of the same system also sends a reminder to customers who've not completed their order after a few days, this is just to check there's no problems with the checkout system, as occasionally bugs creep into the system which only affect some browsers or users. The feedback we get from this is great as it helps improve our service and if there's problems we can get them sorted promptly.
