The most expensive thing I bought on the ah was the Felsteel Longblade pattern for 150k. As a gold farmer I wanted that pattern and was not paying anymore than 150k, when finally someone put the buyout at 150k. Ever since then I been selling the Felsteel Longblade for about 20k each and been getting more gold than paying for it. Worth it!
During Cata I spent a lot of gold getting geared to raid when I didn't have a lot of time to play and loot gear. And, the most on single items I've spent has been on game tokens for game time. I missed getting back on to play by one day, missing my chance at buying a game token. So, being on such a tight budget lately, I haven't been able to play for a few months.
My most expensive purchase was my Spectral Tiger, it was the only thing I really ever wanted in the game and I was able to snatch one up for 175k a few years back. It is still my favorite mount.
During WoD, I found myself getting more gold than I was used to having, so I wound up buying a few pricey mounts to add to my collection. My fave of these has to be the Wooly White Rhino. That mount goes with me everywhere, particularly on my gnome.
I remember when I finally bought Vial of the Sands.I considered 50k to be a fortune back then, needless to say I didn't have that much on all my characters combined, but what I did have was 46146g 59s 67c. A win-win situation of a very happy customer and a seller who happened to be online at the right time.Yep, he got it all, down to the last copper.
Most expensive AH purchase? Can't remember any one thing that's been most expensive. But I do remember when I spent the most gold - start of Pandaria. Had my heart and mind set on becoming Realm First Alchemist, and I had planned ahead so had quite a bit of gold saved up that I spent on buying mats on AH. But I did get my Realm First achiev! So, I was very happy, even though it cost quite a pile of gold ^_~
The most expensive AH purchase I made was on Vial of the Sands for 35k.
A token? Ahahah i dont know if those count(250-300k ish) other than that I've had purchases of about 70k for the sky golem (and other mounts)and yes it was only because of the herbalism perk.
Recently the Steelbound harness mount for about 40k, (found it on sale). Other than that not much, back in wrath spent around 16k for Mechano Hog parts, probably my most relatively expensive purchase given inflation at the time.
I believe my most expensive purchase was a Spectral Tiger Cub battle pet for about 100k which was one of the several remaining ones I required for the Crazy Cat Man/Lady achievement. Otherwise I hoard my gold so that my little goblin might one day bathe in it.
Tokens, really but also I messed up sniping a 100k new battle pet once.
I don't remember the most expensive item i've bought on AH, cause always farm it for myself. So i'm just gonna say the WoW Token (200k maybe 4-5 months ago)
I purchased the Spectral Tiger Cub for my ex. He was always talking about how he regret giving away his mount to his other ex and since I'm not rich enough for the mount I tried to make it up to him by giving him the pet and I don't regret this decision! It was a great purchase and gift!
Purchased that one WoW Token but only once. Still regret it though.
Most expensive but also most worthy - Sky Golem for 300k.
My most expensive purchase was definitely my Spectral Tiger mount for 750k, but it was my most wanted thing in the game for so so long. I still want a Swift Spectral Tiger too still, though! With all the help and advice from this weekly article I'm sure I'll be able to get the gold together and hopefully find one for sale! :)
Jeeze, it's hard to remember. It was almost certainly a battle pet. I think a I spent a few grand on one of the Raiding with Leashes pets but I cannot recall precisely.
I buy many potions and pots on the Ah. But the Most expensive thing i bought are poseidons rains. I think they were about 1 million Gold. But hey its a nice mount :)
The most expensive thing ive bought on the AH is the legendary shoulders which cost me over 50k, sad thing is i replaced em a few weeks after :(
My most expensive purchase on AH was during Mists of Pandaria when ferals needed the top darkmoon fair trinket. It cost almost my entire gold amount (which I didn't have lots of at that moment). Plus, the upgrade things from Inscription makers were required too. Overall, it cost me a fortune but well worth it :D
