Hrm.. well, I call bullshit.
I'm not in the UK, but being a Kiwi there are several items I tend to order every year from the UK for 'cultural reasons'.
I ordered a pile of stuff this year, and it was all in one order. I DO have a Prime account in Germany, but obviously not in the UK.
All 8 items were shipped yesterday. One standard, not express, shipping charge of about 7 euro.
Estimated delivery time - oh, I don't know. Maybe this week, possibly next. Before Xmas anyway. Estimated says this Thursday.
So to those of you wailing and gnashing your teeth - seriously, get a hobby or at least a more vulnerable target for your vehemence because you're boring the shit out of me.
