The surest way to choose a safe online drugstore is to look for the Verified Internet Pharmacy Practice Sites, or Vipps, seal, which shows a druggist has been certified by the National Association of Boards of
Pharmacy, a national group in Park Ridge, Ill., representing the 50 state
pharmacy boards, as well as some outside the country. Most of the big chains such as Walgreens and CVS have internet sites. Drugstore.com is also a registered site.
