Who has all kinds of different yarns, supplies and books?

[KristiMetz]

My mom wants to give me a gift certificate for Christmas and I can't figure out where I want it from.

I was thinking KnitPicks, but if I end up needing something from a particular brand for a pattern, I'd like to have that option, KWIM?

Is there a store, either brick and mortar or online, that would have lots of different yarns, knitting supplies and knitting books that I could choose from?

Since I'm a beginning knitter I don't have a yarn stash, and there's still some supplies I could use, not to mention some books I would love... it would be great to have the option of browsing all types of things, if you know what I mean!

I haven't seen any stores yet that seem to carry all sorts of things, but I'm sure they must exist!
