$100-ish (i forget how much been a wile) for MP prime when he first came out not regretted it at all

 

$225 for a MIB Jetfire...back when i got back into G1.

i was such a noob then.

 

In one transaction? About US$150 shipped for Black Lio Convoy and Black Big Convoy. I still love them a lot! Every time this question is asked, my answer is the same, so I guess I am keeping my spending habit at check...ok that was not true.

 

115 on an Aniversary Prime.

 

Not Sure. Probably only about €55 on a Revenge of the Fallen leader class Optimus Prime. Thats the most expensive thing I've bought personally that's in my collection. €73 if you include the deluxe Bumblebee I got as well.

 

on a single transformer that would be 180 something for predaking. for a bunch of stuff, it would be 200 ish on rotf stuff. i kinda regret that.

 

125 for a complete and nice looking Trypticon.

Sadly i no longer have it.
I needed money and had to sell it.
I hope it's in good hands. I think it went to Canada??

 

over $5000 last year via paypal...paypal sent me some email saying that since i spent over $5000 last year that i got signed up for paypal advantage for free...WTF that is whatever...

 

I can't remember exactly but between $200-$250 for Diaclone Starscream.

 

So far the most I've spent on one Transformer is the reissue Predaking.

But I think the reissue Rodimus Prime will be the most I spend next month.

 

$180 for 2010 Predaking. Before that it was $170 for a MISB Energon Omega Supreme....of course the "value" went down after I tore him out of the package!
