Dealers want about $80 each. Checked last week for my Wagon.
They're dead easy to remove, on inside of the door there are 2 self tappers, one at each end, once removed it unclips.

This is the bitter pill. In korea these are about $8 USD BUT the size or length make freight a killer.
So a set of 4 for my wagon will cost me $136 USD ($190 AUD), still a saving of $130
If you're serious about replacing them and want new if we put an order in together $217 or $109 USD each or $152 AUD which is respectable.
If you're not in SE QLD though adding postage again probably won't achieve anything.
I think any vehicle exposed to lots of UV and heat these are going to blister and perish.
