this really pisses me off.
ive heard similar has happened to a couple of juice vendors with ugly verbal phone threats from here and america and then court threats just because said persons were selling under the rrp. the excuse was complaints from other vendors who were losing money so original manuacturer had to act on it.
Technically they can’t stop you selling it just because you went under the RRP... that could land them in a lot of hot water if you wanted to push it...
