Buy Two discount at Woolworths not a deal

Woolworths Foods offers many special deals on their shelves especially discounts if you 'buy two' you get a big discount. This is great but when you get to the till they ring up your purchase without the advertised discount and most people dont even realize they have been taken. i have been caught a few times. But to Woolworths credit if you notice it and you go back with your slip they will reimburse you # WIN So be very careful at Woolworths when you purchase and check your till slip super carefully
