In stock and cheap price often do not go together.
Obviously if it is cheap they sell out quickly. Therefore if you want the cheapest prices then be prepaired to wait 2-3 weeks for delivery IMHO
I found the best price for my panny 37" plasma by buying 'What TV & Video' mag and phoning/surfing from the adverts (and of course advice from here )
Best advice is - Do your homework, and then do some more.
wow, thats weird. I was about to post a thread here asking the exact same thing.
I'm looking at buying the 37" too, but can't find any shop (not mail order or web based) that sells it. I've tried my local richer sounds but they only stock the 42". I really need to find some shops in Hampshire that sell it so i can get Allders to price match it for me.
