Needed one image - cost $49. They give you an additional 4 downloads which I'm never going to use so it really is just $49 for one image for me.
Then, they subscribe you to auto-renew (without your knowledge) - I saw auto-renew and I thought " you dodgy p*****" - and turned it off... BUT... my payment failed, so I re-entered the information BUT, on failure, they had re-selected auto-renew.
Just a dodgy, underhanded practice...
The prime reason I never use shuttershock and never will.
I decided to just use my extra 9 downloads to download the most popular images and upload them to imgur for free access
