Chilango Burrito Bond 2

Would anyone care to shed some light as to how this is not getting caught by the financial promotion restriction set out in section 21 of the Financial Services and Markets Act 2000?  I assume I am missing something blindingly obvious...

It says the financial promotion is approved by Resolution Compliance Limited

Is it a good deal to buy in though? Presumably they'd have got in to trouble the last time they did it if there was a problem..

Approved financial promotion not required to utilise exemption from requirement to be approved non-shocka
