I've bought from them a couple of times in the past (not for over a year though). Only had any problems once, and that was due to my CC company being over cautious and blocking my card (I had done a couple of very low value transactions earlier in the evening, the third transaction then lead toe the card being blocked.
Unable to sort it out until the morning, then contacted Fotosense about my order - explained what had happened, and that I wanted to proceed - they were able to recall the order, and also honoured the 20% discount that had been available as a weekend special (it was now Monday morning).
I'd be happy to buy from them again.
