After a few emails my order has finally been processed for shipping Wednesday afternoon, and according to the latest email it's being shipped through Amazon and not directly from VegSource. I should have it on Monday.
That's what I get for not just waiting and ordering it from Amazon in the first place, but it didn't appear on Amazon at all until after it was released, so no pre-order was available from them. Next time - and it should be within weeks for Fast Food 4 - I'll wait and order direct from Amazon and save myself this headache. At least Amazon doesn't charge your credit card until they ship it, unlike VegSource that charges you the day you put the order/pre-order in.
