Yes, I think you made a good buy.
The way you store media really depends on its use: long-term archiving, discs to use infrequently, discs to use regularly, etc. There is no one best way to store media. In general, avoiding wallets is a good idea (thus avoid scratches), and avoiding DVD-style cases that warp the disc (as some cheap ones do). In general, quality DVD/BD cases, CD jewel cases, or even study spindles, are the best choice for storage.
I've covered this before, on guides, and in other posts.
