This is my first post. Apologies if I don't do everything to your exacting standards the first time :
Tesco currently have all of the large cans of Dove deodorant for half price - £1.58
If you go to the Dove website and register, you can download a voucher for BOGOF on the Go Fresh sprays. (Link below & credit to Lucerysmum)http://www.dove.co.uk/gofreshdeos#/gofreshdeos/landing.aspx/
When the voucher is scanned, it has a value of £2.79.
So 2 large cans of Dove Go Fresh Deodorant = £3.16 minus £2.79 voucher
I have done this quite a few times this week and now have enough deodorant for a long hot summer.
Hope this helps someone
