Yes, Canadian SM's can contribute to Vitamin Angels. The option will be online or they can donate through Customer Service.
Are contribution's is tax deductible. Here is the correct response:
"Please know that the company does not provide specific tax advise and recommends that SM's consult with an independent tax adviser. If the Canadian SM has income they earn in the US, then they can take deduction against this US income for the contributions they make to Vitamin Angels in the US."
However, most of their income they make from Modere will be Canadian sourced income because they earn it working in Canada. If they spend time in the US earning commission income, that would be US source.
