Raspberry plants or Raspberry canes - a confusion of terminology?

[George the Pigman]

I've been buying raspberry canes recently to go into a raised bed in my plot. You know the ones where you get several canes in a pot then split them out and plant separately. I've bought them before
I rang a local garden centre a few days ago and asked if they had "raspberry canes" and they knew straight away what I meant and said they were getting them in stock in a few days. So I went over yesterday and sure they were in stock but very few summer fruiting ones so I got some autumn fruiting ones . So I just bought Autumn fruiting ones.
Today I rang up another large garden centre a bit further away and asked the same question to get Summer fruiting varieties and they said they were in stock. Took the bus down there and couldn't see them. Asked one of the assistants but he hadn't a clue really what I was talking about. Eventually got to talk to a manager and he took me to a small section of shrub fruit with a few pots containing single raspberry plants in containers at nearly £10 a plant. Certainly not what I was expecting. I asked about raspberry canes sold in the way I'm used to and he said we don't stock them as they don't last. He said he was a professional horticulturalist and  when the single plants grow canes they call them raspberry canes and that was what they thought I was after! Needless to say I was rather miffed.
Never heard of this confusion in terminology before. If you look at a website like say Dobies they specifically distinguish between raspberry canes as I know them and raspberry plants in containers. The latter being of course much more expensive per plant.
Anyone come across this before?

I've also never seen the potted plants referred to as canes commercially. I would always assume canes are bareroot!

An Update and some useful info!
I looked at the raspberry plants/canes today I got from the first garden centre to split the canes into pots. I have found all the Autumn fruiting varieties are actually on a single rootstock with several branches sticking out the soil that lead me to assume they were separate plants .! Only the one summer fruiting variety was a "cane" so I split them into pots.
I rang the garden centre and they said the display consisted of a mixture of separate canes in pots and individual plants. There was nothing on the pots or the display to say which was which.
The most common way one buys raspberry plants is as separate canes. They call them "bare rooted" but they are actually not really as they are in compost!. That's the most common way the producers sell them although some sell a few individual established plants in pots.
So if anyone is asking for raspberry plants to avoid confusion the best thing to ask for is:-
Either: Bare root raspberry canes in compost. Don't just say bare rooted as some garden centres will say "We don't sell bare rooted fruit bushes"!
or: if you want single plants ask for individual plants on a common rootstock in containers.
I've bought raspberry canes twice before from garden centres and never had this problem. Wonder if they are going against the idea of selling them as separate canes they don't keep as well whereas the individual plants in containers last several years.
So now I have to buy some more summer fruiting raspberry canes. I'm going to go online and buy direct from a reputable plantsman who will know what I'm talking about!
Anyone any suggestions?

Sounds like another customer ripoff to me George!  Have you no neighbours/chums that could let you have some?
