you can go really cheap and get used ones but that wouldnt really make much sense.
amazon and ebay are cheapest, then autozone or advanced is the next cheapest.
usually with coil packs you want to replace all at the same time, or at least one bank then the other.

I see you also have a missing gas cap and an evap code.
Tell us the sequence of events.
A bad enough leak in an evap line would cause a lean miss affecting all cylinders. Its not likely that multiple coils went bad at the same time. I'm guessing that all your issues are related. It might be as simple as putting a gas cap on, or replacing the canister valve.

From the gas cap thread;
"Im getting a cap soon but the code was popping up before i lost my cap which when i decided to see if its the right cap and make sure its closed thats when i found out it was missing.
I do have some fumes coming into the car"
You do have a bad leak causing a lean miss, I would bet my paycheck on it. What is your Idle speed?

KS WILL NOT cause a misfire. Bad KS will result in loss of power and lower MPG due to retarded timing. If you had a bad KS and a misfire they were not related. A bad primary O2 will cause a lean miss and triggers a false KS code. Could be what u had.

I got a code for a bad KS and O2sensor and muliple misfire code. The car stalls after driving 1 1/2 miles and than starts up again and runs.. Do you think it is from the the O2 sensor? I changed the plugs about a year ago. Also had an insufficient coolant temp code but I need a radiator. I triied JB waterweld and it didnt work,
Please help. Thanks.

Some people may confuse hesitation with a misfire, a bad KS will make your car hesitate quite a bit, but a misfire is more violent... Unless they're the same thing? Help me out here, when I had a bad knock sensor the car would "bog" or "hesitate" under heavy acceleration but not quite misfire (which to my knowledge you'd get a popping sound).

People need to learn technical terminology before throwing it around out of context.
This is not aimed at aackshun, I see this everyday and its a peeve. I'm not Being the vocabulary police here, we need to use the correct terms to be on the same page.

See what good ol maintenance can do to ya?
I see, we need to make a sticky or update the stickies with videos on showing the differences, I wish I had a video of my car misbehaving with the bad CKPS.
A missfire is an even duh, duh, duh. It is the result of a dead cylinder. It doesn't go away, it only get less noticeable. It should never be confused, nor should the term be sudstituted for hesitation, bog, or stutter.

I have a PO 300 which I thought was random misfire. I also have a PO325 KS which I hope I am only getting because of the random misfire. I believe the O2 sensor is the above the catalytic converter but I did not get a specific code. Would that O2 sensor make the car stall?
