Hi Guys
Remember that CDC's are entitled to charge anything they wish over the RRP as we all operate as self-employed businesses. Also, tetra's do cost us more to stock - as Isobel says - (though the price has not increased since April of this year!) and it is recommended that we charge our clients additionally for tetra's ... however, that is our choice whether we do or do not.
Sorry Lipotrimmer that this does not seem to be in line with what your Counsellor has told you recently but that is the directive from the company.
