Unfortunately we are unable to group together delivery charges from separate orders (made from different sales). We do offer delivery for $3 on subsequent orders you have paid for your initial order.
Due to logistical constraints, you are not able to place items from different sales into the same order. It is also not possible to open two baskets at the same time from different sales.
Although two sales may appear on the website at the same time we do not necessarily receive stock from both suppliers at the same time. For this reason each sale is prepared separately by our Logistics service.
I am sorry that I was unable to assist you on this occasion but if you have any further queries please do not hesitate to contact me.
