But these are the exceptions. Most Americans looking for their prescription drugs won’t find that many deals on the site. Health care is complicated already, and TrumpRx apparently does not always offer the cheapest or best option. Those with insurance—some 85 percent of Americans—typically will get a better deal using the coverage they already have than they would paying out of pocket on TrumpRx. More than three-quarters of Americans with commercial insurance are eligible to pay $20 or less for a month’s supply of Xeljanz, a rheumatoid-arthritis drug. But customers paying cash via TrumpRx will still shell out more than $1,500.
