Yup. Copper is the latest on the ban bandwagon. Ugh. Not just for fish stores. Everywhere. Government seems to think the general public can not be trusted to use chemicals responsibly. Just like certain human medications not being available over the counter. Or needing a vet to write a prescription for most meds for your dog. I had to place an order for meds from the US. Has $225 in my cart. + shipping + tax + exchange rate + $68 duty at the border. dang order cost me almost $400!!! Now copper? Give me a break!
Worst of all they could all be technically seized at the border. So you could spend that $400 and never receive a package.
