May not be a big deal, but people often forget that some medical loopholes exist for US citizens to purchase items through Canada without perscriptions. Perfect example: contacts. In the US if you have wear contacts you have to renew the perscription annually whether it's changed or not. Mine hasn't in years. That being said here are my two favorite sites.
