POA stands for price on application, which for us, just means that the pricing for these products fluctuate often depending on the supply chain etc. This also means that we can't provide accurate costs for our customers unless we provide you with a unique quote for those products.
So if the product you are looking at says POA, "Quote Only" or there is no option to just checkout, that means you will need to contact the team or request a quote at checkout, and one of the sales consultants will provide you with an accurate, up to date price for those products.
