Does that mean Axminster will send your data (name, address, phone number, items browsed and ordered etc) to Facebook, Google, Twitter etc?!
Axminster should make it opt-in for them to share your data with the above, all of which are not essential for processing your order, not you have to opt-out by contacting them before making your order.
The third part review site is Trustpilot. Axminster will send your email address to Trustpilot, then Trustpilot will send you an email asking for a review.
Another company which also does this and might be of interest here is Heinnie Haynes. They bury it in Terms & Conditions but at least has a bit more details than what Axminster says but still does not say they will send your email address to Trustpilot.
Some time ago, I was going to order some fountain pen ink from a well known company. I looked at their privacy policy and it said they will send your email address to Trustpilot after your order, then Trustpilot will send you an email asking for a review. I didn't agree and it seemed there wasn't an opt out. I emailed them and they said there's no opt out saying they have to be impartial and send every customer's email address to Trustpilot(BS). They didn't get my order.
