a retail offer that appears to offer you
something of great value for no extra charge but which really gives you
something which will probably sit in a drawer and
never be used.
2 pairs of spectacles for the price of 1 is a specsaver.
most spectacle wearers know that if they break their glasses they can revert back to their old pair as an
emergency measure especially as a new pair can be made up
in a few days.what usually happens is that the optician will try and use the free second pair as an
opportunity to sell you a coating or tint which you will rarely, if ever, use.
if you visit the optician every 2 years you just end up with lots of unused free second pairs.
