Ok go easy on me as its my first time posting and i haven't tried it (YET) any hoo, by using the 25% off of 6 bottles deal at Tesco at the moment and the fact this bottle of prosecco is £2.49 cheaper at Asda, in theory you can get 6 bottles for £25.53.
Canti Prosecco - Tesco Price = £8.99 Asda Price £6.50
8.99 x 6 = 53.94
- 25% = (£13.47) = £40.47
but then price match will kick in giving you a further £2.49 off per bottle £14.94
TOTAL FOR 6 Bottles £25.53
