Two more odd sized packs for the record.
Tesco supermarket is selling packs of Broccoli with a nominal 335gm ... why? .. so they can sll them at 50p each and display a price of £1.50 per kilo!
A mail order company offered me packs of paper hand wipes (see part 2) with 260 in a pack.

Today I gave blood (it was, according to the records, my 66th time). The UK blood donation service collects a donation of 470ml. Why 470? I asked, being an Elephant's Child with insatiable curiosity (or "'satiable curtiosity" as Kipling wrote).
The service decided on 470 because it was found to be an amount that a healthy donor of minimum weight can safely give; if it were to be increased, then it would prevent some donors from giving. If it were reduced, then handling it (because each donation is divided into parts) might become difficult. So it is 470ml (or equivalent because it is weighed) for good reasons.
