There seems to be a lot of confusion about how our user groups promotions are used. User groups aren't forums, but they allow you to buy replacement parts others can't as well as get discounts on some parts.
User groups are automatically set when adding certain items to your cart.
It doesn't give you a discount on the tool that is added to the cart. The user groups are a way to allow our customers to get replacement parts by just logging into the website.
You must have created an account at the checkout to have the user groups assigned.
