Ok, i'll start by saying this is of course a gamble as it's using the discount codes that others have posted here for LXdirect. But in my mind it isn't a bad gamble as the price is very good even if only the 10% comes through.
First off, be sure to go through quidco if you have an account, an extra 4.5% off the price I mentioned.
First code to enter is: XX494 for 10% off.
Then enter in: ZQ4322 for the £25 off next order(which does seem to be accepted even if paying credit card).
Continue through addresses & total should now be - £50.50!
Of course if using quidco that would make it £48.22, even better!
As usual with LXdirect, you'll be waiting for them to take the full payment, then refund the discount after release, but in my mind this isn't too much of a gamble as for a change the price isn't bad in the first place so not much to loose :)
