See - I know how to grab people's attention!
But this thread is actually how you can obtain free beer. and the proof is here...
How? why? really? I hear you say... well here goes.
Tescos have altered an offer in store this week, from a buy 2 for £16 to £9.98 a crate on Kronenberg. Previously the offer was the same as the beer offers on all crates of 20 bottles (grolsch, hieniken export etc).
The old price labels are still in store in some locations - either big A4 yellow posters or like these, on the end of shelf...
You pay for the goods, can I suggest not using a clubcard, or a credit card, it makes life easier.
Then take the items to Customer services and query the charge. Take the staff member to the displayed price.
Tesco policy is a full refund and to retain the item!!
LEGAL! (ethical maybe not - but legal) remember - every penny helps!
