Personally I think domain(s) are very cost effective - you can purchase one for less than $10 per year and point it anywhere you'd like from the back office.
I looked up your tonisclassics, which is available, not that it's what you want for your domain. Something you can find with keywords for what you sell is ideal, though as Choo says creativity is required.
Put on your creativity cap and start searching. I go to NameCheap just because that's who I've always used, am familiar with their back office and I really like them. Seems lotsa folks go with GoDaddy for some reason. NameCheap is just my personal preference and it's also where I look up for available domains.
Floppy disk... by the time I knew what they really were, they were almost obsolete.
So you're not alone! 
Ask away, ok? I'll be most happy to answer what I can or help ya find th' answer so I can learn too.
