But what about Shell specials!!!!!!?

I think Supercheap have a couple of Saturdays during the year when everything is 20% off.  Last time I bought 2 x Shell Helix Ultra, around $51.80 each or perhaps a bit less.  I have just used one of them and the other is on hand for the next oil change.

Whenever I buy them they're full price.
