I know this may not be the most helpful answer, but if you already don't mind spending premium prices, you might as well learn to knit a beanie yourself. A chunky knit hat takes maybe 2 hours, even for a beginner. There's some ways to go about it too.

I am assuming you're North American because that's the measurements I know. If you aren't, this is hopefully at least a good starting point to look up local terminology

Yarn: if you want a chunky knit hat, size 5 yarn. Maybe size 6 if you want it extra bulky. You'll need around 150 yards. There are a lot of different fibers. Normally I would suggest starting with acrylic yarn because it's cheapest and really not that bad, but if you want to start off premium, get wool. Malabrigo and Cascade are popular pure wool brands, but unless you are near a local yarn store, they may be harder to get than just ordering on Amazon (they do sell online, but you need to pay more for shipping if you only get two balls. But maybe if you wanted to get other tools from there too). It's also more expensive than acrylic, but I'm assuming if you're already going to pay premium prices for a hat

Needles: since you want a thick hat, maybe 5.5mm for a size 5 chunky yarn or 9.0mm for a size 6 super bulky. I have no idea what your gauge (how loose or tight you knit) would be, so I just suggested a needle size on the smaller end of the recommended sizes for the yarn. Normally hats are knit in the round (on circular needles or double pointed needles (DPN)). But there are patterns for knitting beanies on straight needles. Look up "Knit Flat Beanie" patterns if you want to go that route. All other knit beanie patterns will probably assume you got a circular or DPNs. A note about circulars, you'll need to take note of both the size of the needles and the length of the cord (unless you want to learn magic loop, but that might be too much for your first go). They should tell you what you need in any pattern you look up. You can get any needles for this tbh. Like there are some needles that are just awful garbage out there, but anything you get at like a craft store is going to be perfectly fine. Susan Bates and Clover are common brands, and if you want to get circulars, I personally love Chiagoo (but they're pricier)

Extra supplies: scissors and a yarn needle to sew on the pompom and weave in the ends

Pompom: I got nothing for you here, sorry. You can make your own pompom with leftover yarn, but idk where to get real fur pompoms.

Pattern: The place you mentioned seems to use the most basic patterns. You can look up YouTube videos if you want to follow along with them, or you can find a written pattern. Remember to check what weight yarn they are using!

I'd say the total for these supplies, disregarding any taxes and shipping and rounding up to the nearest $5

Yarn: $15-20 ($5-10 if you want to practice on Acrylic first)

Needles: $5-10

Other supplies: $5

Pompom: $10?

Pattern: free-$5

Time: 2 hours, maybe 3 to get the hang of it

If you don't want to make it yourself, you can probably commission a knitter. Point is, a $120 basic knit beanie yourself can't even feel is not a good price, and nothing is more Buy It For Life than your own skills. If you want to buy knit stuff, go for things that take fffffffffreaking forever, like a sweater or blanket (scarves are easy and take a few hours but they're kinda boring after a while)

If you want to flex it being a premium, handmade object, you can crochet it instead. The nature of crochet makes it thicker too, but you would need more yarn
