I ordered trimox form beachrx.com. I ordered 90 so I would have some on hand for the winter. $63.00 total. Overnight shipping. I was not home when they came so I don't know about the quality yet. I have to pick them up at the Fedex hub today. They have a different kinds to choose from. They give a pretty good description on what antibiotic works on different illnesses. I hope they work because I sinus infection no time to go to the doctor.
