Yes they sell microphone's & depending on what style of microphone you need they vary from 13 to about 300 dollars.
Yeah they do, they vary widely in quality and features so i would either call or check it out the website to see if theres one in your price range that does what you need.
If you download the Best Buy mobile app you can find the products they sell by store and that they actually have in stock.
They sell cordless microphones. They have a selection of these to suit different budgets and uses so it really depends on your requirements.
