The best price I have seen in Vancouver so far for a 65" B7 is for the $2,500 I bought it at London Drugs on August 25 for their weekend sale. I called in this weekend on Saturday September 1 to see if the price was lower than $2,500 so I could price match it but the price was $2,500 again.
Over the past 2 weeks the price of the B7 has gone back up during the week to it's regular sale price of $3,000 or $3,100. Depending on the quantity still available I would expect London Drugs to lower their price again to $2,500 this weekend. I will call them again this upcoming weekend to check their price on the off chance that their price is lower than the $2,500 I paid on August 25.
As Euqw alluded to, pricing is subject to inventory still being available. London Drugs had the 55" B7 for $1,700 2 weekends ago but as far as I can tell the 55" B7 is now sold out at London Drugs.
