Agree with the others, glad you are considering trying a fishless cycle Holly!
I'm in the US too (but North Carolina) and I was able to find just the right stuff in my grocery store! I also checked out a local Ace Hardware and it had exactly the right type of ammonia, just as Katty described.
It feels like a weird thing to be out looking for but once you find the right stuff you are set! It also can help to try and get a syringe or similar type of thing with milliliter markings from a drugstore (actually I found two to be helpful as one can be always used for tank water and the other can be always used for ammonia.)
The other important piece of equipment is a water test kit. Most of us like and use the API Freshwater Master Test Kit, it has formed a bit of a lingua franca here in the beginners section so that we can more quickly know what each other is talking about during testing.
There are almost no other chemicals that we use, except a conditioner for the tap water. The one most of us use for that is called Seachem Prime, because it is very concentrated and thus is a great value. The Prime is the thing that removes chlorine and chloramines from the city tap water.
Oh, and an aquarium notebook is a great thing to have. This keeps your daily log of what has gone on with the tank and is still sitting there nicely even if the hard drive fails on your laptop, lol.
