You can also do this search: site:BobsFlowers.com and if nothing comes up, there might be a chance that Google removed it from its search engines. Although in some cases, if nothing shows up it just means that the domain name/website did not have content on it ever or in a long, while so Google never indexed it in the first place, so yeah it’s a bit of a gamble.
Once you’ve determined whether your domain is available, you will want to purchase it from a domain registrar or web hosting company. Some web hosts will register a domain name for you for free (usually for one year) when you buy a web hosting services from them, while others will do it for you, but you’ll have to cover the registrar fees (an annual fee of $10 – $15 for the “.com” domain).
After some digging, The Windows hosting minimum is $3.52/mo if you choose the 3-year billing cycle. Whoever runs their QA needs a dressing down! The Linux at $3.09/mo is accurate, though, if you go for a 3-year billing cycle. The shortest cycle is 6 months, which will cost you the equivalent of $4.32/mo and $3.25/mo for Windows and Linux, respectively.
