Great question. The short answer is yes. The long answer is maybe..
Generally speaking we carry replacement needles for the new brands of turntables that we sell in our store - mainly Crosley & Audio-Technica. If you have one of those brands, we should either have the needle you need or can get you one.
Many other new, mid to upper range turntables also use Audio-Technica needles so you might still be in luck if your turntable isn't one of our brands.
If you have an older turntable with a replaceable cartridge we will likely have a new cartridge you can replace your old one with. The new cartridge will have a new Audio-Technica needle on it - so when you have to replace it again it's easy to find.
