Wow, oil prices went up. I bought two 5 qt jugs at Walmart for like $24, then had like a $9 mail in rebate each, making them $15. This was last year. Looked at Walmart now, the 5 qt jug is 29.97 now, Sam's is about 30 cents per quart cheaper than Walmart right now, I wouldn't stock up on it unless you need it now.
