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.
