I just found the 5 quart containers of Pennzoil Platinum and Ultra at my local WalMart with a sticker on them for an instant $3.00 of at the register. The sticker has an expiration date of 7/31/11, so you have about 5 weeks to stock up if your interested.
My local store sells them for $24.12 for Platinum, and I believe $26.50 for the Ultra before the $3.00 off.
