I did something very stupid.
tl;dr: Assumed FC Primal was out later in week. Thought I had enough time to send back BlackOps3 and order another game, meaning I would still have one slot free for Primal. Turned out Primal is out tomorrow. Ended up upgrading sub just to guarantee Primal being sent out. (Which it was. Just now.)
Assumed Far Cry Primal was out later this week, not tomorrow. Plan on Saturday morning was to send CoDBlOps3 back on Tuesday and, in the meantime, order Ziggurat. They dispatched Ziggurat almost immediately. I have no idea why but, all of a sudden, a panic struck me.
Is Primal out later in the week? I checked and learned I'd got it hugely wrong. So now I have both my slots filled with games I still have; one was winging its way to me even though I could have bought it for all of a few quid in the US PSN sale
, and the other still needed to be posted back, but it was Saturday lunchtime and there was almost no way Boomerang would have got it on time *and* managed to send me Primal. So in the end, my dumbness cost me a little under £6 as I decided to bump my package to 3 games unlimited just for this month.
