Add to cart button without the extra styling

Hi there – how do i create an add to cart button without the price and the border boxes added.

I’ve been using this code which i found in the help forums –

[add_to_cart id = “##” ]
this displays the button the price and has a horrible grey border around
or
[product id = “##”]
this also displays the button the price and has a horrible grey border around as well as a picture
or
[product sku = “####”]
this also displays the button the price and has a horrible grey border around as well as a picture

none of these are of just the button alone

Help paleeese – ive just spend hours trying to work this out – going crazy
