bought a canon 580exii from simply electronics,i went with them as their price was unbeatable at £272.95 and 2% quidco,but after paying on friday,there was no sign of it being despatched by the next thursday despite their claims of delivery in 2-5 days,so i emailed to complain,got a reply next day saying they were trying their best to clear orders asap and upgraded me to express delivery,got an email last night to say the flashgun had been despatched by next day delivery,got it this afternoon,moral of the story:cheapest aint always quickest nor the best,i'll be reluctant to use them again
