I see your point in having multiple configurations and being not easy to post up. I agree with what was suggested above to post certain popular configurations' prices. For example:
1- Model S hood, pre and post refresh (If there is any difference)
2- Model 3 hood
3- Model S both front fenders
4- Model 3 both front fenders
5- A packaged price for Model S (Hood, Fenders, Lights, Fog lights and mirrors)
6- A packaged price for Model 3 (Hood, Fenders, Lights, Fog lights and mirrors)
People respond to simplicity. If they have to PM you to get pricing, that's 1 more step the buyer has to do on something they aren't sure if they are getting any better pricing than their local PPF shops.
We appreciate you wanting to do the community a favor. Hopefully this will not only decrease the number of PMs you have to reply to, but also increase the demand for your pre-cut films. Win for us as a community, win for you as the seller due to increased quantity.
