If I could go back in time and buy one toy, it'd be this Nighttime Rescue Buzz Lightyear.
''
Imagine if Buzz Lightyear was a high-tech Splinter Cell agent. It'd be P E R F E C T. I saw this once but couldn't afford it, and when I earned enough money to buy it, I never saw it again...
Man, back in the Toy Story 2 era (1999 to 2009), they made loads of Buzz toys of all shapes and sizes. It was like getting a new Transformer and it was glorious! And this even included the 10th Anniversary toys where Buzz and Woody were more Movie-Accurate in design and structure, which I also never got but wanted.
I remember renting a copy of Little Samson for NES when it first came out. I wanted that game so bad. It was (and still is) one of my favorite NES games. Turns out it's rare, and now runs several thousand dollars just for the loose cart. Twice that for a complete copy.
It's strange to think about that weekend now. I was 7 or so and playing with a legitimate copy of one of the most valuable NES carts. Should have just "lost" it. Hindsight, right?
Fresh pair of mountainboarding MBS F3 bindings.
A NoSno mountainboard even though it's painfully obsolete
A 2010 or 2012 ticket to Novi Sad, Serbia in September.
My childhood plushie back from my ex!!
This HYPER RARE Bobba Feet action figure that could launch his missile.
It was a legend that we didn't believe was true. Everyone was talking about it but no one ever saw it
In 1979, Kenner pulled the Boba Fett J-slot rocket firing backpack prototype due to a potential chocking hazard. The action figure was replaced with a Boba Fett and solid, non-mechanical backpack. The J-slot prototype is up for auction at Hake's in York; the toy is expected to sell for close to $250,000.
Sailor Moon metal pencil case I saw at a school fair where we bought books every year.
It looked amazing and I am literally still thinking about it after 20 years 
I always wanted the barbie that closed her eyes using hot/cold water because she had a soft fabric body and super cute pijamas. 
Or this Ken that shaves 🪒 he we as my crush.
I'm thinking about buying him on ebay. But I have too many dolls already and there is no room for it 
And comics... I would love the Pocket monsters comics. They came randomly inside a box full of candy and had a figure of the monsters, sadly you couldn't pick.
These or anything Ojamajo Doremi related
I grew up watching the 4kids version of the show and there were commercials for the wandalers and dream spinners. Apparently there were witchling costumes too. I wanted them soooo bad, but they were never in my local stores. I could only find the little dolls that I didn’t really care for.
It was also disheartening when I found out that Magical DoReMi was actually Ojamajo Doremi and it’s original run ended before the 4kids dub (Who only aired 20 episodes and marketed in a way that was obvious they weren’t doing the other seasons). Any hope of getting the other magical items were squandered since Japanese toys are crazy overpriced.

I would buy a retro Nintendo Game Boy from the really first version. I actually have one, and that's nostalgic af. As it's retro and I don't really want to damage it I use with some accessories like upper cases. I've mine on the aliexpress where u can also find some retro stickers, cards and whatever u actually want. Btw I would strongly recommend u using a tool that sorts the offers by the best prices and the suppliers' trust factor. Here is link to it.
I've seen the Barbie you're talking about! She's super adorable. Tho there's no such thing as too many dolls 
Good luck in your search
the Laputa the castle in the sky pendant I saw at Ghibli Museum back in 2016
but I was on a budget and couldnt afford to buy it oTL
Ive seen copies on internet but this one is the most beautiful, the pic doesnt make it justice to see the real thing
Pokemon Emerald when they were currently being sold and released at like $50. Beautiful money to be earned off legit copies of those right now.
I would have gone back and never bought a single physical game from Xbox 360 and PS3 onwards... I still have my accounts, and now the PS3 store is closing. I have to try and rebuy games I already owned physically, while the store glitches out and denies my card. Sony won't fix it.

Definitely the Operation Aliens action figures
Apparently, back in the 80s, they were planning a Saturday morning cartoon about Aliens (the film).
There was a wave of figures released, and they're so cheesy, I just love them. They were released before I was born, so I wouldn't have to worry about time paradoxes either!
No Vasquez though
at least 3 1st edition Charizard's when they first dropped and keep them mint....Reason...I like money, also to get rid of all financial worries and invest.
