We sell the same pads, and we always beat any price. They need filing to ensure they fit correctly. If you can't manage this yourself, step away from the spanners and let someone do the job for you.
The FCP565H DS2500 pad is larger than the alternative, thus a better choice. Due to the coating on the backing plate, they are too tight a fit in the CS carrier. Just file or grind the top and bottom tabs slightly, to allow at least 1mm of up and down movement in the carrier. There are LOADS of threads about this, just do a search. Also, throw the shims away.
