Tired of getting "hosed" by big name dental supply companies on the Canadian side of the border. One box of impregum is now almost three hundred bucks... a five pound jug of acrylic runs 350 bucks. My arse hurts... but I can't afford Anusol.
Pearson Dental is a good source. Also a Google and E-Bay search periodically may yield good results. We have had to endure the increases of that big name, the past three years, too. . Pearson will ask for payment up front with a card.
