My mum printed off a voucher with her Boots advantage card this week for 100 points if you buy certain cold and flu remedies. Calpol is included and reduced to 99p, so with the 100 bonus points and the 4 points you get for spending 99p you are 4p up and have the Calpol for "free". Also the machine let her print 7 vouchers, but she did have to keep going to different tills with her Strepsils etc. Not sure if everyone will get this voucher if they put their Advantage Card in, but worth a try.
