6) If your credit limit was below £723 you need to call them straight away and pay the difference with a CC or Debit card (eg my credit limit was £650 - so i called them and paid the £73 difference on my card)
7) Wait for quidco to pay you the £55 cashback (takes around 3 months) - Note quidco membership costs £5 a year - but this money is taken from your earned cashback - you never actually pay them anything!
Total discounts:
£1099 discounted to £799 on the website
£799 - 10% from discount code = £719
Quidco on Ex.VAT amount (719 / 1.175 = 611 : 9% of 611 = £55) £719-£55 = £664
+ Delivery charge = £664+£3.50 = £667.50
Add a fiver to that figure if you are not already a quidco member
And you get the option for interest free credit! (or just pay it all off if you want)
Hope someone can make good use of this, its the best price I could get!
