all of those offers or similar can be found using Google, and you dont have to pay for that?
including 10% off Bugaboo.com, £100 off Octopus energy when you switch, 3 months free superfast broadband with Zen, £80 John Lewis voucher when you sign up to Admiral insurance and up to £100 off holidays with Holidays Please.
Here's the Octopus one, its £50 off, by using a referral link - ( I know your one is £100, but in reality so is this one, just split by 2 households)
How does it work? Use my Octopus referral code by following the link when you switch to Octopus Energy. After you pay your first bill £50 will be credited to your octopus energy account.
Once you have chosen to switch to Octopus Energy as a new customer, you ’ll be given £50 credit on your first bill and your own personal referral code to share with friends and families. For every person that switches with your code, you both get £50 credited towards your next bill. It takes just two minutes to switch and your code is effective immediately. (I would be delighted if you use mine to get you started, thank you!)
