Fake Himalayan Salt

[StudMuffinsMissus 10]

I bought a 25kg bag of Himalayan salt on BoB which I received today. It has clearly been mixed with regular coarse salt. I supply an online company with products made with Himalayan salt and resorted to buying online only after my regular supplier was out of town. If you work with the salt a lot it's pretty easy to spot the real thing and it tastes very different as well. Question is...if I return it do I pay the R196 postage? So annoying
