Trigger Shot

I'm curious how much everyone's meds have cost them! We switched doctors and after a few different EXPENSIVE tests my dr wants us to try IUI with more aggressive drugs! Anyways, I went on to compassionate care and we qualified for 50% off of our meds so I was super excited! Anyways, when we had done our previous IUIs I always had to order the trigger shot and it was roughly around $100 and got Chlomid from the pharm.  Well I went to get an estimate on our drugs for this next cycle (higher dosage of gonal-f and an HCG shot) and the guy told me the trigger shot was going to be $999! The 50% off program only works for the gonal F so all together my meds are going to be close to 1300! Are there different trigger shots? I'm just in shock and curious what everyone else pays for their medication!
