The regular price for 5-quart jugs of Pennzoil Platinum at my local Walmart is $19.99. The AutoZone price is only a "sale" if you want the free filter, but I'll pass on Frams, thank you very much!

I got the guy at Autozone to give me an AC Delco filter instead of the Fram. Sometimes they will and sometimes they won't. I usually get it because the Delco is about 3 dollars cheaper, it saves them money and makes the customer happy.
I 'tried' to take advantage of the AZ sale, but they don't carry filters (in the sale model) for the Ecotec and wouldn't substitute (even for a less expensive filter). He said the computer wouldn't even let him enter it for the sale... Whatever!
I knew I was in trouble when I first asked for the filter and the store manager was dumbfounded when I said 'cartridge' and 'ectotec'. He had no clue!!! I guess that's why I've only been to AZ 3 times in my life and likely won't be going back, no matter how good the sale is.

… does Platinum have the parafin in it? ...or whatever that waxy [censored] is that is in the petro version of Pennsoil?
One has to distinguish between a paraffin and paraffin wax -- a paraffin isn't necessarily a paraffin wax. A paraffin is a saturated hydrocarbon (C-H) -- this includes Group II, III and even IV base oils (PAO's). In chemistry they are known as alkanes. Even Group I base oils used for motor oils are generally mostly paraffins but they also contain a significant amount of other things like aromatics -- cycloalkenes (alkenes). The more paraffinic (having the properties of a saturated hydrocarbon) a base oil is the better it is for making motor oils.
If you look at the CAS number for Group II/III …
64742-54-7 ... Distillates (petroleum), hydrotreated heavy paraffinic.
… they are called paraffinic base oils (paraffinic is the adjective of the noun paraffin).
Paraffin-wax (~ C25-H52) refers to the longer chain hydrocarbons that are solid at room temperature. The smaller chained hydrocarbons are gaseous at room temperature (2Carbons - ethane, 3C - propane, 4C- butane), and as one gets longer chains they become liquid at room temperature; oils like Kerosene C12 - C15 are also called paraffin oil, and finally the longer chained hydrocarbons (paraffins) become solid at room temperature (wax) around 20 Carbons (the straight chain ones).
There is paraffin wax in a barrel of crude oil (depending on the source of crude) but the wax is removed in the refining process to produce base oils (even in Group I's). If one goes back far enough (~ 1930's) at some point they didn't have the technology to remove the wax from crude oil on an industrial scale, so, many motor oils would indeed have had a significant portion of paraffin wax molecules in them. But that was a long time ago in a galaxy far far away …
Interesting enough, the dewaxing of motor oils on a commerical scale got going in the 1930's …

… Though the wax-based oils of Pennsylvania were the leading motor oils, their use was limited because at low temperatures the wax hardened. The Govers process allowed people to operate automobiles in lower temperatures.
In 1931, Texaco acquired control of Indian Refining and the rights to Havoline® Motor Oil and the Govers process. Over the next three years scientists worked to improve the oil and discovered a solvent extraction process using furfural. This process, along with the solvent dewaxing, could use any source of crude to produce a quality motor oil. The new technology caused business to expand rapidly, and the following year, an expanded lubricants plant in Port Arthur, Texas, helped to accommodate the increasing demand. The Texaco refinery at Lawrenceville, Illinois, first introduced Havoline® Motor Oil in 1934. Today, the solvent dewaxing process and solvent extraction process are the chief methods of refining motor oil throughout the petroleum industry. Currently, these processes are under license of the Texaco Development Corporation….

Its chemists and engineers (led by Dr. Francis X. Govers) having perfected a
revolutionary solvent-dewaxing process, INDIAN REFINING COMPANY introduces
“HAVOLINE WAXFREE” motor oil, replacing “HAVOLINE –the power oil” (which had,
early in the 1920’s, supplanted "HAVOLINE It Makes a Difference”). (An economy
"Blended HAVOLINE" is also offered, primarily in bulk.)
