Was in tesco getting some Aero 5 packs after seeing the deal posted by "dontdothatagain" and i noticed they had some 5 + 2 free bar packs in the normal sweet isle, these were marked up at £1.79 but i thought it was worth a try scanning them and they scanned at 3 for £3! so instead of the bargain 15 bars for £3 you get 21 bars for £3.
These were the original chocolate Aero and were in the chocolate/sweet isle not on the end of isle special 3 for £3 display
Thanx to op for me finding this deal, original post:http://www.hotukdeals.com/deals/nestle-5pk-9pk-sweets-aero-kit-kat-/731959#comments
