How to buy hydrogen peroxide

There are different types of hydrogen peroxide available online, such as 20% potent hydrogen peroxide, 25% hydrogen peroxide,  35%hydrogen peroxide being shipped in one, two, three or four gallon packaging, and why is that? Because if this four gallon limit of hydrogen peroxide is exceeded, the resulting solution becomes a bit too toxic, and it can corrode the packaging while it's on the way to be delivered. There are other usages of this concentrated solution too, for example, a diluted form of this solution can be used to clean minor cuts and scrapes, you can also buy food grade hydrogen peroxide if you want to clean vegetables and fruits, or chopping boards that are frequently used, although it needs to be in diluted form, else it can be corrosive under some circumstances.
