they have been around for years. Good company. This deal is only really a deal if you don't cancel until second month as it's basically buy one month get one free
Going off the address on the contact page it is this company - http://stores.ebay.co.uk/simplyssupplements/Contact-Us.html - https://uk.trustpilot.com/review/www.simplysupplements.net
Looks like a con to me. Read the terms and can't find any company number displayed on their website.
Looks like it is chargeable if you cancel unless I'm misunderstanding their T&C's ?? http://www.simplysupplements.net/mynutripack/terms-conditions/ You can cancel your subscription any time. If you cancel within 25 days from receipt of your order, you will be charged the full recommended retail price of your first pack but you will not be charged for or receive any further packs. If you cancel after 25 days, you will be charged the full recommended retail price of your first and second packs but will not be charged or receive further packs.
