By buying their products you are agreeing to the T&C and thus explicitly agreeing that you are acting as a business and thus "forfeiting" consumer rights.
Wow, that's how it works? The website just needs to have the words "for business use only" and they avoid all consumer rights laws?
No it's not how it works. In fact the law says that terms and conditions need to be reasonable. You can't just add all kinds of rubbish to suit your needs.
That line made me laugh, it's total bollocks.
"Thus" ...that implies that businesses have no legal protection when they buy stuff, which would, for example, spell doom for all retailers who are businesses who buy everything they sell on to consumers who have rights that they don't?
. Businesses are protected too, just not the same way/level and that "protection" often requires lawyering up.
