Hey,
When I ordered the workbook, I got an order confirmation email shortly after placing my order. The next day, I got an email confirming they had dispatched the order and received it following day after that. There was no parcel tracking as far as I could tell.
I was surprised to receive it so quick actually but I would say be patient. I think when I placed the order, delivery was estimated between 5 - 7 days so if it takes longer, I would try contacting their Facebook or Twitter directly but if its only been a day or two then its still well within their estimated delivery timescale.
Hope you receive it soon! It's well worth the wait.
Cheers,
Tj
Edit:
I took this snippet from their help and support page (https://affinity.store/en-gb/help/) if its any help:
