[disqQ]

I appreciate your thoughtful input.

Actually checked a bit of their terms and was able to see this excerpt:

Products that are opened and have been used are eligible for website credit (issued in the form of a e-gift card). Additionally, customers found abusing or manipulating this program will forfeit the ability to return opened items and potentially future orders. Eligibility for this program will be determined at the discretion of Bowmar Nutrition. We do issue a $9.99 processing fee that is subtracted from your store credit.

but in my case this does not interest me.

I'm following your advice on contacting them first to see their response.
If going forward with this, they also allow payments with Paypal so this is a plus for my side.
