Canon G1X with Free Case and voucher

[tomita.alo]

Hi,

received an e-mail from Wex Photographic few days back. they are offering the Canon G1X with a leather case for £629.10. voucher code: WEX10CANL2

http://www.wexphotographic.com/buy-...black-digital-camera-plus-free-case/p10001629

very tempted to buy one. confused, whether to go for an Interchageable lens or G1X.

any advice?

thanks,
