Just that. But it has to be that you personally paid the most money for; no good counting a $150 book that was on sale for $15 (unless $15 is the most you ever paid for an RPG).

It will mostly be recent stuff - I paid I think £45 for Tome of Beasts not long ago, I think that must be the highest single purchase. I was lucky enough to get the Wilderlands of High Fantasy Box set for around £27 in 2007. Generally with the weak pound, US $50 hardbacks are getting up around £50 here now.
Putting together a Pathfinder Adventure Path has cost me around £80-£90, but that is 6 individual books.

150 bucks for a copy of the boxed Empire of the Petal Throne.

$80 for the two-volume set of HERO System 6th Edition.

For a single item? Probably the Ptolus book.

I've paid more for miniature sets/boxes (I think it was $150 for the Bones kickstarter, $170 for Starfinder Sodapop minis, and I think the first Pathfinder Battles case was like $350. But that's dozens of minis.)

Over the Edge 20th Anniversary Edition ('round 100$) or maybe the Delta Green Eyes Only Volume 2: The Fate (80ish $), bought a couple of years before Pagan Pub collected all three Eyes Only-books in the big Delta Green: Eyes Only. I think my Ptolus-book only set me back around 65$.

I think it was $50 for the leather bound Hackmaster 5E. Waste of my money frankly. But I like the idea of owning a leather bound RPG book.

I paid $96cdn for Horror on the Orient Express...

If single item, Ptolus.  That was, what, just under $150 done in three installments?  I don't remember exactly.  I did buy 11 copies of Cook's Arcana Unearthed as a bulk purchase, but got a sizable discount because it was a bulk pre-order that pushed the FLGS's initial order into discount territory.  Ended up being about $23 to $25 per book.

Dwarven Forge, A friends D&D miniature collection, GURPS Dungeon Fantasy ($250), and the newer OD&D premium Collectors Box in that order.

Frankly at this point I am not interested in any more large purchases including Dwarven forge. I only put in enough in the last kickstarter to cherry pick some unique pieces I liked.

$134.17 last year, for a copy of the Judges Guild City-State of the World Emperor along with Wilderlands of High Fantasy & Frontier Forts of Kelnore- an Ebay sale. Considering I own the complete Judges Guild Wilderlands collection now, that was a real bargain!

The most I ever spent in one go on multiple games was in the Autumn of 1981. I had spent the three months of summer working at ranch in the Rocky Mountains of Wyoming, and returned to Colorado Springs to start school in the Autumn. I had saved several thousand dollars over the course of the summer, and when I got into town hit the local hobby shops all up and down the front ranging from Fort Collins, all the way down to Colorado Springs and went on a spending spree, ending up spending about $1100 in three days on RPGs and boardgames. I think every gamer should do that at least once or twice in their life, go on an all out spending spree and buy everything that one wants, that is available, for gaming.

Gaming Conventions are expensive. Not the RPGs, or other games, as I'm usually badged for GMing, or as a staff volunteer. However the travel, lodging and food expenses for attending, are significant. UCon last year this time set me back $600, GaryCon last March about $500 as well, and Origins $145 (One day only-Badges, travel & food). This was before I dropped a dime on any gaming publications, or accessories.

Back in June of last year, I put together about ten or so proposals for games (of which I would submit four to run for the show) and then email them to the RPG director of UCon, and asked him to pick one that he would like to see run at his show. My plan was to pick the one he wanted me to run, as well as three others, and of course, run those games at the show. I received a rather terse reply telling me to submit the games directly (as if I didn't know how to even register for a convention).

So I'm not sure where the communications crossup occurred, because I had no plans at all to run twelve sessions of games for a four day convention, and just wanted to be friendly and maybe run an old school game or two that they would really like to see at their show. They could have even asked me to run something not on the list, and I would have been delighted to comply, however all I got was a couple of emails stating "submit the games you want to run to the website registration process"  Since both RPG coordinators couldn't be bothered to name even one game of the dozen that I had selected to run for them. I decided to save my $500 and not attend UCon this year.

I'll probably still end up spending that money on games, ...of course, have to keep my budget on track...

Is Ptolus was $150 that probably was the largest. I also purchased the Classic Rune Quest all Digital level in kick starter, that's several books though a single purchase option, so dunno if that counts.

Necromancer's Wilderlands of High Fantasy box set, sealed, long after it had been released. $300 iirc.

Hmm, I thought it'd be Dungeon Fantasy Kickstarter, but I checked and I only coughed up $50 for that. I paid more for the English-language Aquelarre kickstarter ($60), but probably a better answer would be if you consider the GURPS 4e Basic Set, which comes in two hardcover books with color pages to get what in earlier editions was one book or set - I don't remember what they cost at the time but current list would be $85 for both books.

I'm sure you didn't mean computer RPG's, but I did get Omnitrend's Universe about 1985, which cost $89.96 in yesteryear money, though technically it was a Christmas present from Grandma, and not "really" an RPG, though I did play it as a team with a P&P RPG friend for a bit.

I shelled out $175 for Arc Dream's Delta Green Rpg Kickstarter. The core book, and a bunch of pdfs.
