I had an email through with the following discount codes for this weekend:
(finishes midnight 31st May)
BONANZA15 to get 15% off £50+
BONANZA20 to get 20% off £100+
BONANZA25 to get 25% off £150+
Becareful tho as they seem to put prices up before they offer discounts so shop around to make sure you are getting a deal and not conned
hope it saves someone some money!
