No probs hun. Doesn't matter as long as you use the correct address (the normal one or the Premium one). I wouldn't recommend doing extra fast postage as mine only took a couple of weeks, and we have ages to go yet. xx
Heya. I went to WHSmith and did a £7 quid recorded one. Doesn't really matter. If you want to, you could just do a normal first class stamp. I just don't have a post office nearby and I like to pay a little more to get it tracked/sent quicker.
