Problems with Aliexpress Choice shipping

Hi. I wanted to know whether anyone has managed to place an order since Saturday/Sunday using the Choice Delivery promo. It’s meant to be free delivery if you spend minimum £8 on the products within the Choice range and was working perfectly fine until Saturday where even though the free delivery shows at checkout for me, as soon as I click pay, a message comes up saying that it’s expired and the shipping fee has been added so I don’t proceed with the order.

I’ve contacted them but got different responses each time. I was told I’d be contacted by the technical team but so far I haven’t been.

Just wondering whether I should just do a large order for everything I want as at least that way I’d only be paying 1 lot of shipping.
