Mari is right.
You print out the coupons...

On the site, you start by putting in your zip code, then the name of the med, and you put in the dose and number of pills you need for 30 days.

Then you will get a list of pharmacies in your area and the cost of the med there if you use the coupon. Click on the pharmacy you want, and print out the coupon for there.

Then you just take his script and present that coupon when you go to pick it up.

If the XR is too expensive, you can try asking his pdoc for a script for regular Seroquel because there are equivalents, and it’s better than him not taking any.
