Hi,
Wait, you said that you didn't want taxes ?
Do you mean that you want taxes of 7.25% only on the products ?
That's possible. You need to have one tax rule in the menu System>Taxes configured on the default tax category with a tax rate of 7.25%. Then, you just need to make sure your products have their "tax category" set to the default tax category so that the tax rule will apply to them.
If you're having trouble with these, please provide a screenshot of the settings of a product for which it doesn't work and a screenshot of what you have in System>Taxes.
