tbh ive had issues with pricecharting since it pulls in fake or broken games too often. its not as good as expected when youre on a tight budget. terapeak is frustrating on mobile but unfortunately its the only one i trust for accuracy.

• use eBay terapeak for the 90 day trend data
• avoid checkaflip since it misses too many listings
• double check every deal manually to stay safe

Adding my two cents here because I spent way too much money on fake carts when I was starting out in the Chicago area. You gotta be super careful with those sold listings because a lot of what you see on the surface is actually fake or reproduction games that people list as authentic. I once dropped fifty bucks on a deal that ended up being a cheap knockoff from overseas because I didnt check the board photos properly. If youre using free tools, keep these things in mind:

• Look for the discrete versus lot pricing because a bundle of 5 games will mess up your single-game average.
• Check the seller location; sometimes prices are lower from certain countries but shipping makes them irrelevant.
• Watch for relisted items that never actually sold but show up in some databases anyway. Honestly, just take your time and dont rush into a buy because a graph looks green. Pokemon games are basically a minefield of fakes right now, so if a price looks too good to be true, it almost always is. Just make sure to double check the actual listing photos before trusting any trend line...

I've spent way too many nights diving into the raw sales data for retro handhelds! Its seriously amazing how much a clean label or a battery swap affects the final hammer price. I used to use those basic web scrapers but they kept missing the Best Offer Accepted prices, which totally ruins your margins! To get the most reliable data, I started using this eBay price tracker because it actually visualizes the trend lines so you can see if a spike is just a one-off or a real market shift. ^ This. Also, you should definitely focus on the Sell-through rate percentage instead of just looking at the total number of sold items. If its under 50 percent, the market is getting way too crowded and you might be sitting on that inventory for months! Data is king when you only got 200 bucks to play with.

Regarding what #2 said about Adding my two cents here because I spent...

• honestly that happened to me way too often when I was starting out. I thought I was getting a steal on a bundle of Fire Emblems once and it basically wiped out my whole month profit because they were total junk repros. Over the years, I've tried many ways to track this stuff, and I've learned that relying on just one source is a recipe for disaster when you're working with such a small budget. In my experience, you really need a workflow that filters out the noise:
• I always look at the 90-day trend lines first to see if a price is just a fluke or a weird spike.
• Checking the actual photos of sold listings is non-negotiable to spot those fakes before you buy.
• I stay away from anything that looks too good to be true without seeing the internal board. Actually, PriceDropCatch is pretty solid because you dont even need to make an account to use it. My current setup is basically just being patient and verifying everything twice. It sucks when you miss a deal but its way better than losing your 200 bucks on a brick. Just keep at it and dont rush into a purchase just because youre excited... the right deal will come along eventually.

Just saw this. Like someone mentioned, the mobile interface for Terapeak is pretty much trash, but honestly, it is the most accurate because it shows the actual price after a Best Offer was accepted. Most free sites just show the original asking price, which is gonna lie to you every time. In my experience, you gotta be careful with these three things:

• pricecharting often includes lot sales which makes individual games look way cheaper than they are
• checkaflip misses most of the high-volume weekend sales
• avoid any site that doesnt let you filter out parts only or broken listings manually If you're worried about Pokemon Emerald, dont just look at the line going up. Check how many are actually selling per day. If the price is rising but the volume is dropping, people are just being greedy and nobody is actually buying. Ive tried many ways to track this and raw volume is always more important than a spikey graph. Lmk if you need help looking at a specific listing tho.
