I seem to be unable to get the current customer group price for a product.
Product is set up with a standard price of £20 and a 'wholesale' group price for 1+ units at £10.
On a category page (when logged in as a wholesale customer), I correctly see the struck through price and £10 beside it.
However, I want to show an icon when a customer is getting a special price because of their group.
$product->getPrice() returns 20,
$product->getFinalPrice() returns 20,
$product->getSpecialPrice() is null.
I'm trying to get the current group customer price (10) in a variable, so I can compare it. Is this possible? If so, what function do I need to use?
