Somebody in the family recently was given a prescription for an ointment.  A little tube cost $158 at Wallgreens.  I went home and searched for the same exact thing at Drugstore.com and found it for $40 including shipping.  I noticed the company that made the product was in Canada.  I have heard that many drugs cost less in Canada, but never expected it to be 1/4 the cost.  That is 75% off the Wallgreens price.
