Lots of my FB friends seem to be doing it. Obviously, £500 is quite a nice lot of money to get, but I'm wondering
a) is it genuine
b) do you end up having 'Liked' Tesco so that you get them in your news feed all the time - can you 'unlike' them afterwards to stop this?
c) if you get the voucher do you have to spend it all in one go or can you use it over several lots of shopping, can it be used on Tesco Direct etc as well?
Thanks!
