Spotted this 24 hour deal on Quidco today, open a new Stocks and Shares ISA with Nutmeg by depositing £500 lump sum then a minimum of £100 a month to receive £180 Cashback after 3 months.
Not a bad return if you are planning to take an ISA out.
Cashback rates seem to fluctuate between Topcashback & Quidco but this appears to be a decent offer, as of 16/02 Topcashback has a lower cashback amount of £172.50 - not sure what rates will be after tomorrow.
As its a Stocks and Shares ISA your capital is at Risk and they have certain ISA rules which will apply so make sure you read the T&C's carefully before proceeding as you may not get back what you invest.
Their terms are available here;https://www.nutmeg.com/faq
Note: You must apply for the ISA through Quidco or Topcashback, not directly through the Nutmeg website or you won't get the cashback:-https://www.topcashback.co.uk/nutmeg-stocks-and-shares/http://www.quidco.com/nutmeg-stocks-and-shares-isa/
Kudos to "norbie" for a similar thread last year on Stocks & shares ISA's.
Edited 20/02/2017 - offer now on Topcashback @ £180
