I just stopped by my CVS to pick a small one up for my purse so I can take my meds at work. They have a huge variety, like they had an entire back wall dedicated to CVS branded pill organizers of every size and color imaginable.
The most intense one that I saw was this JUMBO, 4 a day set: http://www.cvs.com/shop/home-health-care/other-daily-living-aids/medicine-accessories/cvs-mega-pill-planner-skuid-429374
I swear it was the size of a binder, I was like "WOAH, WHAT THE WHAAAAAT
" when I saw it hanging on the rack hahaha.
