Unable to Order new Printer

Hi there I am new to the world of 3D Printers and I am trying to order the A250T on the website but it keeps giving an error saying the discount code does not work. I have not used a discount code and I am not planning on using one. Is this because of the Halloween Sale going on right now. Does anyone know how to fix this issue?

It’s on sale, so it won’t be available.
I thought it was the same in all stores.

So due to the sale I am unable to order? I’ll just wait till its over I guess.
Thank you!
