An attempt to respond to a bargain with this online only firm will lead to HOURS of your time being wasted. They offer apparent bargains BUT there is always a catch as in my case: here I was offered two pairs of glasses for £49 (the second pair being free) but after countless attempts to order the second pair I had to resort to calling them (in the Philippines!) and was told that by the nature of my (very ordinary) prescription I could only proceed by paying an additional £99 to complete the order! These are scam merchants and should be avoided like the plague!
