This is a strange one - I purchase these speakers about 3 weeks ago via the 'reserve & collect' option on the PC World website. I paid £44.99.
Today I went to PC World at Lakeside, looking for something else and just happened to walk past the speaker aisle and was amazed to see these beauties for £34.99 !!
The strange thing is that the website now shows them at the original price of £69.99.
I hope someone finds this useful, as it must be just a special offer instore at Lakeside, Thurrock !!
