In addition to the previous updates, we have also updated our Bulk Add Items page, where you can easily paste a list of SKUs and quantities then quickly add them to the shopping cart without searching for each item individually.
One major update was for duplicate SKU, previously the quantities for repeat SKUs were not taken into account, the update now sum all the quantities of repeat SKUs.
When using the Bulk Add Items always double-check your basket and quantities before placing the order.
