Better off googling it, I'm no good with a computer but this might work
If you are a new customer (or just set up a new account) you can use the discount code EXPO-10, for a further 10% discount, makes Starter Sets £17.99, Imperial Aces £19.32 and Tantive IV £50.35 (good rates for the UK), everything else you can buy cheaper elsewhere.
They always have free postage over £10. I use them for all my X-Wing stuff. Some of those prices arnt just for this sale, a lot of the time their aces/large ships are way cheaper than most places.
Just ordered through them, using the EXPO-10 code but its messed up and charging me for postage now (have mailed their customer support). Be vigilant if you order from them, as without free postage they aren't that cheap 
I think you have to register an account to get the free postage.
Which i did, and during the shopping cart view it was showing the postage deduction, but when i went to pay it then added full price postage. I'm hoping it's a technical oversight/issue on their part as Amazon payments seems to be new for them.
From what I can remember your postage refund is added to the code discount total, as long as you select the cheapest postage option.
Tritex games is in general cheaper across the board.
