According to the Royal Mail website, it seems I'm paying as a 35gm letter, rather than a "small packet". It seems they define an "airmail letter" differently to an inland letter, so that there's no extra for size or shape. I'm confused!
"Letters and postcards
You can send postcards and Letter items up to 2kg in weight via the Airmail Letter service. A Letter item is anything that contains personalised correspondence.
This Airmail service offers you a cheaper rate if you’re sending gifts, goods or commercial samples. When using this service, please write ‘SMALL PACKET’ in the top left corner on the front of the item you are sending. You can also include a letter relating to the contents, but no other personalised correspondence."
I'm about 20 miles from Nottingham, so I hope you haven't snaffled all of Boots K64...
only joking! I really have enough for my needs now, I pass Meadowhall on the M1 every few weeks, so I've been stocking up at Boots there. The manager commented last time "It's supposed to be discontinued, but it keeps arriving from the warehouse!"
One of the junior staff warned me of the last date for processing, which I thought showed good customer awareness.
MX2 had K64 last week, and 7dayshop were showing "Stock - Plenty" yesterday.
