If it's a digital version, it should say "PDF" or "Download" or "ePub" at the end of the product title, but I do sometimes miss it. The product availability tag at the bottom of the page is the final answer though—digital versions are always available immediately after purchase.

Yeah - it was entirely user error. I didn't even twig when I wasn't charged any shipping.
I'm sure you guys labelled it correctly - I just got overly jumpy at the virtual table top reference. Thinking about it now, I needn't have bugged you about it anyway. I could have just look at the estimated shipping time and charges. Thanks for clarifying for me, though.
