Bonus deal is from Panasonic, so use any of the stores included in the promotion.
Free 5 year warranty by redemption and also a choice of 10% cashback or 32gb Panasonic SD card. If you take the cashback
This is a pretty amazing deal for a camcorder that gets fantastic reviews.
The 5 year warranty is the clincher. I have had various problems with Sony camcorders just after warranty period, so knowing that this will last you 5 years is the sweetener.
The SD card is the RP-SDQ32GE1K which is a Panasonic class 6 32gb card, retailing at £100 on amazon.
You need to have demonstration of the camcorder and have the claim form signed I think, which makes online retailers not an option.
I will put the links in the first reply.
