Thou $43 for 2x5L jugs isn't bad but PP is often on sale at $27 or so at CanTire or WM and then there is $10 a jug MIR. I used that deal a few times, actually all last several times I bought PP I used the deal and MIR came thru.
I'm most def buying it at $33 for 2x5L jugs.
I haven’t seen PP on sale for 27 bucks for awhile though. Probably Since Boxing Day. Also I don’t see the rebate online anymore.
Walmart and NAPA had it on sale somewhat recently, you need to check online flyers since WM that I went to still had full price on shelf price tag while oil was on sale and at discount on check out.
Penn doesn't seem to have a promo at the moment, check often - every 2-3 weeks or so.
Edit: also, use phone App called Flipp
to search for deals, e.g. type in 'synthetic motor oil'.
