Just been in to take advantage of the Buy 1, Get 2 Free offer, and the main display was only for :
Salt & Vinegar
Cheese & Onion
All priced at £1.99 each. I didn't want C&O, so went and picked up some Texas BBQ flavour from the crisps aisle (they were priced at £1.45). When they went through the till, I expected to pay £1.99 for the three tubs (with 1 @ £1.99 and 1 @ £1.45 being free).
However, the till deducted £3.98, leaving me paying £1.45 for the three !!
Looking at the receipt (which says *Pringles Offer* -3.98) it also seems that this is a standard reduction at the till. Therefore, it works if you buy 3 tubes of Texas BBQ or Salt & Vinegar (or any others which don't have the yellow flash showing that they contain approx 90 crisps), which were also £1.45 you'll end up paying just 37p for all three !!
