I've been looking at the G20 for some time, prices seem to be fixed at £799.99. The difference with this deal is you get a Panasonic DMP-BD85 Blu-Ray player (£130 on Amazon) for FREE. Plus 3 free Blu-Rays, see link in post #1.
As you'll notice the price is actually £999.99, to get the £799.99 price you'll need to enter the voucher code '20TVLOW' (valid until 26/08/10, credit to millarcat).
I plan to sell the BD and use my PS3 which will hopefully net me £100 back, and thus £699.99.
Available for collection (no payment required until collection), or home delivery.
