Discount vat in the carta and other option for the black friday

[ballashop]

Hi, I'm looking for a module to buy that allows me to discount VAT.

We have different ones likes  10% 22% etc..., so the module should only disable the VAT in the cart.

So into the cart I need the price without tax. I also need to diversify the discount depending on the payment method used by the customer.

In practice, if the buyer pays with PayPal the discount is applied while with bank transfer no. For me this option doesn't make sense but the shop owner wants likes this.

Furthermore, the offer is valid only over a minimum amount, even shipping cost is free over an amount, but this can be done without buy a module.

Ideas and suggestions? Thanks for any replay.
