Can an order be edited/added to at the picking stage

Hi there. Does anyone know if this is possible? I’ve placed an order but there’s something elese I’d like to add to it. Is this possible? I can’t see the option anywhere?

Any help much appreciated.

You can try emailing; but bear in mind that it’s Sunday so they are unlikely to respond until tomorrow!

Thanks for that. Yeah it’s annoying it’s Sunday. I don’t want to miss out on the other item as it’s on sale. Might have to put the order in and see if they’ll be able to combine the two orders tomorrow and reimburse me the postage. Hope so as it’s a bit daft you can’t do it if the order is still sitting on packing. Or even let me cancel the order and redo it to include the extra item.
