Hi Kokomo,
I can't speak for other dealers, but PX here is run along the lines Peter detailed.
It has been well covered elsewhere on this Forum, but just to recap - there is a PX offer, just ending, that was organised centrally, whereby a minimum PX value was offered to anyone with an older B&O TV ( it had to work, and have a functioning remote). The "cost" of this PX offer was split between the dealer and B&O.
If you have a very old TV ( 70's and 80's tube sets) then obviously the PX value of £500 was superb, as the market value of these sets (other than to collectors) is about 50p - in reality, most would have been scrapped by the owners, or given away, rather than sold. So getting £500 for one was a real bonus.
As the TV offered for PX gets newer, the offer gets less generous, but even then its not bad - think about a 28" Avant VCR - most here know its still a stunnning TV, particularly for a bedroom, second room or for kids games consoles etc- but ask any 5 or 6 random people you bump into if they will give you £500 for an eight year old 28" tube TV, with a built in VCR, four feet high and a two-man lift, and once they finish laughing, they will point you to the nearest ASDA /Tesco/Comet, and the latest no-name LCD for £300 or less. Sadly, you would struggle to give it away to many people. Their loss, as we know, but still the truth.
After this offer, PX will be a negotiation, based on what you are buying and the resale value of the product you want to change.
There are VAT implications for dealing with PX products that prevent your scenario of just being able to "pocket the profit as a sort of perk" ..., aside from paying the bills, retailers carry out a secondary role as tax collectors !
All in all, its a good time to get a CRT, either as a main or secondary TV - and not a bad time to PX one.
Best Regards
