Most major hardware stores, Home Depot, Lowes, etc.
All garden and supply stores. You can probably get way more than you need for really cheap. Say a giant package for $5-10. Any more and it's probably more than what you need to pay for.
Basically, look for 100% peat moss, or spaghum peat moss. NO additives such as fertilizers of any sort should be listed in the ingredients. It's really simple to find these extra unwanted ingredients, they're usually printed in big letters in the front labelling as marketing to attract buyers.
As well, before using it on the main tank, first test the level that pH, GH, KH will drop by--peat moss varies from region to region, depending on where it was supplied from. Apparently the chemistry behind peat moss is really complicated. So the tannin colour in water is not a good indicator of its pH reducing capacity.
Oh yeah, peat moss tends to be hard to wet initially, it likes to float at the surface. Just pour hot water and everything should settle.
