you never pay the price advertized with them it's just a sweetener to get you through the door I woulfd always go to the independent opticions better run and a more personal service

I'm sorry to be so cynical but I have studied the high st prices and the independant is invariably more expensive. I have had a long chat to more than one Spec Savers store and the feeling I get is that though they have various offers which may overlap and generally you can't have more than one, they wil always try to get you the best for what you want. IE if you have that offer then you pay less than with that offer.
To me it makes no sense to try and annoy customers. Obviously if you know about spectacles you know it's quite complicated (lens types & thicknesses and then single vision/bi or varifocal plus other variations), so you can't expect someone to promote 420 different varieties in a headline! Specsavers are genuinely better value (and try tobe clear) and their offers always genuine - for example the two-for-one where you get the same quality twice, unlike at other stores - how else could they survive with everyone keeping such a close eye on them, being the number one opticians!
