Where to buy electronic components now that RadioShack is gone?

I'm curious, with the recent news of RadioShack's closure, where can one now find a reliable source to purchase electronic components? I used to rely on them for my hobby projects and DIY electronics, but now I'm left wondering where to turn. Are there any online retailers or brick-and-mortar stores that have emerged as the go-to for enthusiasts like me? And what about the quality and variety of products - can I still expect to find what I need at competitive prices?
