My local game store sells individual dice for 50 cents, so you can get your standard seven-piece set for 3.50, plus an extra two quarters for that second d6.

That said, it's from a segmented bin that hasn't been refreshed in years, so the only sets left in it are the ugliest ones that no one wants. Still, getting all the dice you really need for less than $5 means that if you download the rulebooks, roleplaying winds up being one of the cheapest hobbies you can devote yourself to.

If you want one of those packaged sets of 7 dice, they're sold for $10, which is a lot just for six dice, but you're guaranteed to get exactly what you want. It's sort of a vanity thing, since it's all just a matter of choosing s color you like, but even then it's still not breaking the bank for something that can provide years of entertainment. I still have the dice from my very first set which I got nearly two decades ago.

If you're a gambling person, you can always buy one of those $20 pound of dice that they sell online, which is typically enough dice to provide for you and like, ten players. With luck, you might actually get some really nice sets.

I bought one of those bags of 100 dice, and wound up with three really nice sets, and a couple okay ones, and four of the ugliest sets I had ever seen. They were so ugly, that they were perfect for "loner" dice for players who forgot their dice at home.

So, altogether, you can get different dice for different prices, and if all you want is functional dice, they're pretty fairly priced. There's expensive dice out there, but those are premium dice, and only worth it if you really, really like them.
